Super Junior (Korean: 슈퍼주니어; Japanese: スーパージュニア; Chinese: 超级少年) is a South Korean boy band formed by S.M. Entertainment in 2005. The group debuted with 12 members: Leeteuk (leader), Heechul, Han Geng, Yesung, Kangin, Shindong, Sungmin, Eunhyuk, Donghae, Siwon, Ryeowook, Kibum and later added a 13th member named Kyuhyun. As of September 2011, eight members are currently active,[1] due to Han Geng's lawsuit with S.M. Entertainment which led to him leaving the group (now pursuing his own singing career in the Mandarin pop entertainment industry), Heechul and Kangin's temporary leave of absence for mandatory military service, Siwon's filming for his upcoming drama Poseidon (in which shooting of the drama are located at the farthest areas of South Korea, making him to temporary halt his activities with the group)[2] and Kibum's pursuit of an acting career.[3] However, the other members have insisted that all four (Heechul, Kangin, Kibum and Han Geng) are still part of the group, despite mentioning that they are saddened by Han Geng's departure from the group.[4][5]
Super Junior has released and contributed 20 records with varying degrees of success.[6] Over the years, they have been divided into smaller subgroups, simultaneously targeting different music industries and audiences. Largely due to Super Junior's success as entertainers, other Korean entertainment managements began to train their music groups in other areas of entertainment, such as acting and hosting.[6] In addition to their commercial success, Super Junior has earned twelve music awards from the Mnet Asian Music Awards, eleven from the Golden Disk Awards, and is the second singing group to win Favorite Artist Korea at the 2008 MTV Asia Awards after jtL in 2003.[7]
Pre-debut
In 2000, the company held their first overseas casting auditions and discovered Han Geng in Beijing, China, who was chosen from among three thousand applicants.[8] That same year, Yesung was discovered under Seoul's casting system. Sungmin and Donghae became trainees after jointly winning the first place in Best Outward Appearance in an S.M.-sponsored contest. In 2002, Heechul and Kangin were recruited along with Kibum, who was discovered in Los Angeles, California. Siwon was encountered in 2003 after being scouted at age 16 in front of his high school, and Ryeowook in 2004, in which the latter was discovered through the Chin Chin Youth Festival singing competition.[9] In 2005, Shindong was selected. The last member, Cho Kyuhyun, was then discovered after winning third place at the Chin Chin Singing Competition in 2005.
Not long after boy band TVXQ's debut in 2003, news about Lee's unprecedented plans of forming another boy band quickly spread on the Internet. In early 2005, Lee confirmed the news and announced that an all-boy project group of twelve members would debut near the end of the year, promoting this singing group to be "The Gateway to Stardom of Asia."[10] Lee announced that that most members in this group were chosen because of their performing experiences as actors, MCs, models, and radio hosts prior debut. Heechul and Kibum were already established entertainers, and most of the other members had already made various kinds of appearances on television and media.[11][12][13] Highly inspired by the rotational concept of Japan's girl group Morning Musume, this group would also experience line-up changes, with new members replacing some selected members every year to keep the group constantly young and all-rounded. This concept was then newly introduced to the K-pop market.
For a while the group was rumored to be called O.V.E.R, the acronym for "Obey the Voice for Each Rhythm."[14][a] However, before the group settled with their current name, S.M. simply referred to them as Junior, a representation of the members' young ages when they first became S.M. trainees.[14] After the members' showcased their different talents to the company at a picnic, the company finalized their concept name to Super Junior. The group thereafter became officially Super Junior 05, the first generation of Super Junior.[9] Leeteuk said on Star Golden Bell that "at first, Super Junior's name was S.M. Junior, but after Lee Soo Man saw our performance, he said we have super talent and quickly change our name to Super Junior".[citation needed]
Super Junior 05 made their pre-debut on the Korean channel Mnet on September 11, 2005.[b] At the showcase, they performed various styles of hip-hop dancing, where they danced to B2K's "Take It to the Floor". Han Geng, Eunhyuk, and Donghae also performed a separate dance away from the group, dancing to Usher's "Caught Up." However, the performance did not air on television until May 16, 2006, as a segment in the Super Junior Show, the group's first television documentary.
2006–07: U, Don't Don and breakthrough success
On May 23, 2006, S.M. Entertainment revealed the thirteenth member Kyuhyun, who was discovered through a singing competition in 2005. They released their single "U" online for free download on May 25, 2006, on their official website. "U" had over 400,000 downloads within five hours of release and it ultimately exceeded 1.7 million downloads, crashing the server.[19][20] The physical single of "U" with a total of three tracks was released on June 6, 2006, eventually selling over 81,000 units.[21] The single became one of Korea's most popular songs of the year, yielding number one spots for five consecutive weeks on two of Korea's top music programs.[22] By the end of the year, Super Junior collected over seven awards in five of South Korea's top music award ceremonies, winning the title as Best New Group of 2006.
Super Junior's first sub-unit, the ballad-singing trio Super Junior-K.R.Y., debuted on November 5, 2006, with a performance of Hyena theme song "The One I Love" on KBS music program Music Bank.[23] A second sub-unit arrived in February 2007 called Super Junior-T. The trot-singing group released their first single "Rokuko" on February 23, 2007, and made a debut performance on Popular Songs two days later.[24]
Super Junior's second official album was intended for a late 2006 release, but due to several accidental setbacks, Don't Don was not released until September 20, 2007.[25][26] Within the first three days of release, offline album sales for Don't Don passed the 11,000 unit mark, debuting as number one in all available offline charts. It finished the September monthly album sales as number one. 60,000 units were shipped by the first week of release and additional copies were printed.[27] Although Don't Don received rather bland reviews from critics, the album sold more than 160,000 copies by the end of the year, becoming the second best-selling record of 2007.[28][29][c] The album also found success in Taiwan; it broke the record for being the highest ranked Korean album on the G-music Combo Billboard Chart, surpassing the albums of TVXQ and Shinhwa. Super Junior's album also ranked above Taiwanese boy band K One, whose album debuted at number six.[30][31]
Supported by the release of Don't Don, Super Junior was nominated in seven separate categories at the 2007 Mnet/KM Music Festival that was held on November 17, 2007. Super Junior won three of those categories including "Netizen Choice Award" and "Mobile Popularity", being the biggest winner of the night. The group also won "Best Artist of the Year" (Daesang), termed by many as the highest recognition of the ceremony.[32] Super Junior collected two more awards on December 14 at the 2007 Golden Disk Awards.[33] Although defeated by SG Wannabe in winning the "Daesang", Super Junior won a "Bonsang" and the "TPL Anycall Popularity Award", which were reported as expected wins for the group by the media after the success of Don't Don.[33]
2008–09: Beyond Korea and Sorry, Sorry
On October 2, 2007, S.M. Entertainment announced a third Super Junior sub-unit Super Junior-M, a subgroup designated for the Chinese market.[34][35] While the creation of the subgroup created a brief controversy between the fans and the management,[e] Super Junior-M became a success in China,[36] having the opportunity to have two sold-out concerts in Hong Kong,[37] top weekly ratings with their appearance on variety programs,[38] and becoming the idol group with the most endorsement contracts in China.[39] With the absence of almost half of the members in Korea, a fourth Super Junior sub-unit was created that same year to prevent Super Junior from disappearing in the Korean music industry. With five members from Super Junior-T and Yesung, they formed the subgroup, Super Junior-Happy. Super Junior-Happy released the extended play (EP) Cooking? Cooking! on June 5, 2008, and promotions ended on September 7, lasting for four months. In November 2008, Super Junior-T returned, this time as a singing group in Japan, called SuperJunior-TxMoeyan; this group added Moeyan, a two-woman comedy group in Japan.[40] "ROCK&GO", a Japanese-language version of "Rokuko", debuted at number 19 on the Oricon Daily Charts[41] and ascended to number 2 three days later.[42]
Super Junior's first major tour, Super Show, commenced on February 22, 2008, in Seoul.[43][44][45][f] The tour covered three countries and had shows on six different cities, including Bangkok, Shanghai, and Beijing.[35][44][46] From July 8 to July 9, 2008, Super Junior held their first fan meeting in Japan, at the Nippon Budokan in Tokyo, as a celebration for the grand opening of their official Japanese homepage, which was launched on April 1, 2008.[47] 12,000 tickets to the fan meeting were all sold out in several days. The group released a compiled Japan single the following day, entitled "U/Twins", which includes the Japanese version of "U" in the limited release, to complement the event. The single peaked at number four on Japan's Oricon Daily Chart in its first day of release, and dropped down four places in its second. The single broke a new record for being the first Korean single to have made within top 10 on Japan's Oricon Weekly Chart.[48] On August 2, 2008, Super Junior expanded their routes to Genting Highlands, Malaysia, being one of the top guest performers at the MTV Asia Awards 2008 along with other international performing artists such as OneRepublic and the Jabbawockeez.[7] They are the third SM artist to win Favorite Artist Korea at the MTV Asia Awards after Kangta of H.O.T and BoA, and the second musical group to win the award after JTL in 2008.[7]
Super Junior's third album, Sorry, Sorry, was released on March 12, 2009, which was met with acclaimed reviews.[49] The title single of the album, "Sorry, Sorry" was digitally released on March 9, 2009.[50] In less than a week after pre-orders were announced, over 150,000 copies were pre-ordered.[51]Sorry, Sorry was their first album to debut at number one on the Hanteo Charts, and it sold over 29,000 copies the first day, defeating Seo Taiji's record of 25,000.[3] Promotions for the album started March 13 with the performance of "Sorry, Sorry" and "Why I Like You" on Music Bank.[52] Two weeks later, "Sorry, Sorry" became the number one song of the week on the same program.[53] During the group's performance on music program Popular Songs on March 15, ratings went up to as high as 14%, the highest in recent years.[54] From March to May, "Sorry, Sorry" collected a total of ten number-one awards with consecutive wins in Korea, having the single becoming a national and international success.[55][56] After only a month of release, the album became South Korea's best-selling album of 2009. Sorry, Sorry was also a critically and commercially successful hit in other Asian countries, opting the group to become the only overseas representative for the second time at Taiwan's annual Golden Melody Awards. "Sorry, Sorry" was also number one for a record-breaking 37 weeks in Taiwan. Sorry, Sorry was a best-selling Korean-language album in Taiwan,[57] Thailand, China, and the Philippines, in which the latter listed the album to be the first K-pop album to reach number one in music charts from the country.[58] Super Junior won three awards in the 1st Mnet Asian Music Awards - Overseas Viewers Award, Mobile Popularity Award and CGV Popularity Award despite not attending. On December 11, 2009, Super Junior's Sorry, Sorry won Daesang at the 2009 Golden Disk Awards, their first in the group's career.[59] They held their second Asia Tour Super Show 2 start in Seoul on July 17, 2009, and ended in Manila, Philippines on April 10, 2010.

They broke the record for having the highest single album sales for a Korean idol group when their single albums that were released in Japan sold combined total of over 100,000 copies (including those sold at Circle K Sunkus and Mu-Mo),[74] until it was surpassed by fellow label mate Shinee with their debut Japanese single "Replay (Kimi wa Boku no Everything)" at the same month. To date, Super Junior holds the highest record for singles released set upon by a Korean group without any promotion in Japan. [75] Beginning May 16, the song was shown on major Japanese television channels as the commercial song for Japanese convenience store chain Circle K Sunkus.

2PM adalah boy bandKorea Selatan yang berada di bawah manajemen artis JYP Entertainment. Pada awalnya grup ini terdiri dari 7 anggota, namun sekarang hanya terdiri dari 6 anggota. Jaebeom mengumumkan dirinya keluar dari 2PM pada September 2009, setelah adanya kontroversi mengenai komentar negatif yang dibuatnya mengenai Korea lima tahun yang lalu diketahui publik.[1] Sekarang 2PM terdiri dari Junsu, Junho, Nichkhun, Taecyeon, Wooyoung, dan Chansung.
Bersama-sama 2AM, 2PM adalah salah satu dari dua subgrup yang dibentuk dari boy band One Day. Grup ini pertama kali melakukan debutnya pada 4 September 2008 dengan lagu "10 Jeom Manjeome 10 Jeom" (10점 만점에 10점) yang menonjolkan gaya tari akrobatik dan b-boy
Tentang 2PM awal karir masing2 personilnya
25 Februari 2010 lalu JYP Entertainment memastikan Jae Bum tidak mungkin kembali ke 2PM karena kontraknya dengan JYP telah dihentikan secara permanen. Selanjutnya 2PM akan melanjutkan kegiatan mereka dengan enam personel, yakni Junsu, Nickhun, Taecyeon, Wooyoung, Junho, dan Chansung. Berikut profil singkatnya: Junsu: Hampir masuk grup 2AM
Pemilik nama lengkap Kim Junsu ini memulai karier bukan dari kontes menyanyi. Ia lebih banyak berprestasi di lomba puisi dan menulis lagu. Namun bukan berarti kemampuan menyanyi kelahiran cowok 15 Januari 1988 ini tak bisa diandalkan. Andai tidak memilih masuk ke JYP Entertainment, ia mungkin akan jadi bagian dari grup Big Bang, bersama dua sahabatnya, Taeyang dan G-Dragon. Namun Junsu punya pertimbangan lain sehingga memilih bergabung dalam proyek JYP. Konon Junsu semula dipersiapkan untuk grup 2AM (mulanya personel 2AM dan 2PM sama-sama tergabung dalam grup One Day). Ia juga sudah melakukan latihan intensif selama enam bulan untuk persiapan debut 2AM. Namun entah mengapa pada akhirnya JYP bengubah keputusan dan memasukkan Junsu dalam 2PM. Nickhun: Wajah China-Thailandnya bikin gemas
Aih, lucunya personel yang satu ini. Tak hanya di mata penggemar, di antara personel 2PM, ia dikenal paling pandai memainkan ekspresi wajah menggemaskan. Pada awal kemunculannya, Nickhun salah satu personel paling menarik perhatian. Wajah imut perpaduan China-Thailand cowok yang lahir dan besar di Amerika ini dan kemampuan berbahasa Korea yang masih minim bikin geregetan. Pemilik nama lengkap Nickhun Buck Horvejkul yang lahir pada 24 Juni 1988 ini ditemukan JYP di Amerika, saat cowok yang terdaftar sebagai warga negara Amerika ini ikut Korean Music Festival di Los Angeles. Kemampuan beradaptasi Nichkun yang baik di Korea membuatnya makin berkilau. Kemampuan bahasa Korea yang makin fasih menjadi jalan memperlancar kariernya. Tahun ini, pemilik julukan Prince Khun ini akan merambah dunia akting dengan menjadi pendukung film The Shining Diploma. Taecyeon: Bagi waktu antara akting dan 2PM
Meski orang Korea asli, Taecyeon pernah berdomisili 7 tahun ke Bedford, Massachusetts. Pengalaman melanglang buana di negeri orang membuatnya menguasai empat bahasa: Korea, Inggris, Spanyol, China. Kelahiran 27 Desember 1988 ini pernah ikut acara audisi musik yang sama dengan Junho dan Chansung, Superstar Survival, namun menjadi kontestan pertama yang meninggalkan acara. Saat ikut audisi JYP di New York, sebenarnya ia berniat menjadi model atau aktor. Di tangan JYP, Taecyeon berhasil dilatih menjadi rapper keren di 2PM. Tapi keinginannya menjajal dunia akting terwujud. Ia dipercaya memerankan karakter Jungwoo di serial Cinderella’s Sister dengan lawan main Moon Geum Young. Lalu, apakah jadwal syuting Taecyeon mengganggu kegiatannya bersama 2PM? Jelas tidak. “Kami sudah mengatur jadwalnya dengan syuting Cinderella’s Sister selama hari kerja, dan kegiatan 2PM di akhir pekan,” kata perwakilan JYP. Wooyoung: Giat belajar bahasa Inggris
Jang Wooyoung personel 2PM yang ditemukan JYP lewat audisi Mgoon. Ia mengalahkan sekitar 5.000 peserta dan keluar sebagai pemenang. Sebelum memulai debut di 2PM, Wooyoung pernah menggantikan TOP-nya Big Bang untuk menari bersama Yoobin Wonder Girl di acara MBC Music Awards. Ya, selain menjadi salah satu vokalis utama 2PM, Wooyoung menonjol dalam koreografi. Personel kelahiran 30 April 1989 ini pernah menjadi co-host acara SBS Inkigayo (bareng Taecyeon) dan acara talk show Win Win. Ketertarikannya mempelajari bahasa Inggris cukup besar. Konon, Wooyoung menambah satu kosa kata bahasa Inggris setiap hari. Dulu, saat Jae Bum masih bergabung, ia sering bertanya kepada Jae Bum, apakah pelafalan bahasa Inggrisnya sudah benar atau masih berantakan. Junho: Nyaris keluar dari JYP
Jika Taecyon dan Chansung gagal di acara Superstar Survival pada 2006, Lee Junho keluar sebagai pemenangnya. Tapi siapa sangka, kemenangan itu tak lantas memudahkan jalan Junho. Ia nyaris putus asa saat mengikuti pelatihan di JYP Entertainment. Saat hadir di acara variety show SBS Strong Heart, ia curhat tentang pengalaman pahitnya awal menjalani pelatihan. Predikatnya sebagai pemenang audisi Superstar Survival justru membuat banyak peserta pelatihan lain menjauhi. Yang lebih menyakitkan, ia nyaris keluar dari JYP hanya karena postur tubuh yang dinilai kurang sempurna. Saat persiapan debut, personel dibagi dua kelompok: kelompok tinggi (Im Seulong, Ok Taecyeon, dan Hwang Changsung) dan kelompok pendek (Jae Bum dan Jo Kwon). “Tapi aku tidak bisa masuk ke grup mana pun dan keluar dari persyaratan,” kenang dia. Dukungan semangat dari sang bunda menguatkannya. Ia terus berusaha membuktikan kemampuannya. Dan terbukti, penyanyi yang disebut-sebut mirip Rain ini mampu memperkuat komposisi personel 2PM. Chansung: Dua kali audisi
Hwang Changsung vokalis dan rapper 2PM yang usianya paling muda. Tak seperti personel lain, ia memulai dunia keartisan lewat jalan akting. Serial Unstoppable High Kick menjadi debutnya. Meski bermodal pengalaman akting dan wajah ganteng tipikal idola remaja, penyanyi kelahiran 11 Februari 1990 ini harus dua kali audisi sampai JYP mencium potensinya. Selain paling muda, Changsung juga dikenal sebagai personel 2PM yang paling doyan makan dan pengendus aroma makanan. Changsung pernah diprotes habis para fans di Korea karena terlihat membuang sampah sembarangan saat muncul di sebuah reality show. Tapi sekarang enggak diulang lagi, kan?
Profil: Nichkhun lahir di Rancho Cucamonga, California, warga negara Amerika Serikat keturunan Thai dan Tionghoa. Masa kecil dihabiskannya di Thailand dan California, serta bersekolah di Selandia Baru. Sekembalinya di Amerika Serikat, agen bakat JYP Hollywood, California menemukannya ketika Nichkhun–waktu itu murid Sekolah Menengah Atas Los Osos–sedang melihat Festival Musik Korea di Los Angeles.
Pada Sistem Tenaga Listrik terdapat penggunaan komponen elektronika yang umumnya dipakai dalam rangkaian pengaturan motor-motor listrik. Komponen-komponen elektronika yang dipergunakan pada sistem tenaga listrik pada prinsipnya harus mampu menghasilkan daya yang besar atau mampu menahan disipasi daya yang besar.
Elektronika daya meliputi switching, pengontrolan dan pengubah (konversi) blok-blok yang besar dari daya listrik dengan menggunakan sarana peralatan semikonduktor. Dengan demikian elektronika daya secara garis besar terbagi menjadi 2 (dua) bagian yaitu :
1. Rangkaian Daya
2. Rangkaian kontrol
Pada gambar berikut menunjukkan hubungan antara kedua rangkaian diatas yang terintegrasi menjadi satu, dimana keduanya banyak memanfaatkan peralatan semikonduktor.
Rangkaian daya terdiri dari komponen Dioda, Thyristor dan Transistor Daya. Sedangkan rangkaian kontrol terdiri atas Dioda, Transistor dan rangkaian terpadu (Integrated Circuit / IC).
Dengan menggunakan peralatan-peralatan yang serupa keandalan dan kompatibilitas dari perlengkapan (sistem) akan dapat diperbaiki. Elektronika daya merupakan bagian yang penting dalam industri-industri, yaitu dalam pengontrolan daya pada sistem, proses elektronika dan lain-lain.
I. DIODA
Dioda merupakan penyatuan dari lapisan P dan N sebagaimana gambar struktur dan simbol lapisan.
Syarat dioda dalam keadaan ON adalah Vak positip sedangkan untuk OFF adalah Vak negatif.
Karateristik tersebut menggambarkan hubungan antara arus dioda (IR dan IF) agar Vak dalam kondisi menahan arus (OFF) maupun dalam keadaan mengalir (ON). Dalam keadaan OFF, Vak = Vr = negatif, maka dioda menahan arus namun terdapat arus bocor Ir yang kecil.
Dalam keadaan ON, Vak = Vf = positif, dioda mengalirkan arus namun terdapat tegangan jatuh pada dioda = ∆ Vf, dan jika ∆ Vf ini makin besar untuk arus dioda yang makin tinggi, berarti rugi konduksi If * ∆ Vf naik. Terlihat pula pada karateristik dioda diatas bahwa bila Vr terlalu tinggi dioda akan rusak.
Karateristik Switching
Karateristik ini menggambarkan sifat kerja dioda dalam perpindahan keadaan ON ke OFF dan sebaliknya.
Dioda akan segera melalukan arus jika Vr telah mencapai lebih dari Vf minimum dioda kondusif dan pada saat OFF terjadi kelambatan dari dioda untuk kembali mempunyai kemampuan memblokir tegangan reverse. Dari gambar diatas tgerlihat adanya arus balik sesaat pada dioda, dimana arus balik ini terjadi pada saat peralihan keadaan dioda dari kondisi ON ke kondisi membloking tegangan reverse.
Dengan adanya sifat arus balik, maka diperoleh dua jenis penggolongan dioda yaitu :
1. Dioda Cepat, yaitu dioda dengan kemapuan segera mampu membloking
tegangan reverse yang cepat, orde 200 ns terhitung sejak arus forward dioda
sama dengan 0 (nol).
2. Dioda Lambat, yaitu untuk hal yang sama dioda memerlukan waktu lebih lama,
Q32 > Qs1.
Terminologi karateristik dioda
Trr : Reverse Recovery Time, waktu yang diperlukan dioda untuk bersifat membloking tegangan forward.
Tjr : Waktu yang diperlukan oleh Juction P-N untuk bersifat membloking.
Tbr : Waktu yang diperlukan daerah perbatasan Junction untuk membentuk zone bloking.
Qs : Jumlah muatan yang mengalir dalam arah reverse selama perpindahan status dioda ON ke OFF.
Dioda jenis lambat banyak digunakan pada rangkaian konverter dengan komutasi lambat/natural, seperti rangkaian penyearah. Sedangkan Dioda jenis Cepat dipergunakan pada konverter statis dengan komutasi sendiri seperti misalnya pada DC Chopper, konverter komutasi sendiri dll.
Kemampuan Tegangan
Dioda bersifat memblokir tegangan reverse, ternyata mampu menahan tegangan tersebut tergantung pada karateristik tegangan itu sendiri.
VRWM = Puncak tegangan kerja normal.
VRRM = Puncak tegangan lebih yang terjadi secara periodik.
VRSM = Puncak tegangan lebih tidak periodik.
Kemampuan Arus Dioda
Adanya tegangan jatuh konduksi ∆ Vf menyebabkan rugi daya pada dioda yang keluar dalam bentuk panas. Temperatur junction maksimum terletak antara 110°C - 125°C. Panas yang melebihi dari temperatur ini akan menyebabkan dioda rusak. Temperatur maksimum ini dapat dicapai oleh bermacam-macam pembebanan arus terhadap dioda.
If (AV) : Arus rata-rata maksimum yang diijinkan setiap harga arus rata-rata akan menghasilkan suatu harga temperatur akhir pada junction dioda. Batas If (AV) ini juga tergantung pada temperatur ruang dan jenis sistem pendinginan (Heat-sink).
If (RMS) : Harga effektif maksimum arus dioda. Harga rata-rata yang di bawah If (∆V) maksimum, belum menjamin keamanan operasi dioda terutama arus beban dioda dengan form factor yang tinggi. ( Rate Mean Square )
If (RM) : Harga puncak arus lebih periodik yang diijinkan.
If (SM) : Harga puncak arus lebih non periodik yang diijinkan
T : Batas integral pembebanan arus dimana dioda masih mampu mengalaminya.
Besaran ini berlaku untuk ½ cycles atau 1 ms dan merupakan pedoman dalam pemilihan pengaman arus.
