Rectifier diode - sharaxaad ka mid ah xuduudaha iyo sifooyinka

Rectifier diode - qalab elektaroonik ah diinta hadda joogto galay talantaalli hadda ah. Tani waa aalad laba-koronto ah, taas oo uu leeyahay hal hab oo kaliya (unipolar) conductivity korontada. diode Rectifier qalabka Semiconductor iyo kuwa lagu magacaabo buundooyinka diode (marka afar dioska- ku xiran yihiin ku qotonta oo laba laba ka mid ah ay dhacdo) bedelay ignitron iyo diode vacuum.

Saamaynta of sixitaan ee talantaalli ah ee hadda jira iyo waxa loogu badalo galay guurka si joogta ah dhacdaa ee Semiconductor-birta, bir-Semiconductor ama waxa loogu yeero guurka electron-dalool ee kiristaalo qaar ka mid ah (tus, Silicon, germanium, selenium, xabagta copper). kiristaalo noocan oo kale ah ayaa inta badan u sameeyaan ku salaysan qalabka.

diode rectifier Semiconductor loo isticmaalo qalabka korontada, elektaroonik ah iyo qalabka korontada. Dhab ahaantii, toosinta ah - Isbadal this talantaalli ah ee hadda (danab) inay hadda ah mid ka mid polarity (gaboowday DC). Noocan ah sixitaan u baahan tahay in farshaxanka for furitaanka iyo xidhitaanka wareeggeedii korontada, bedesheen iyo ogaanshaha ee signallo koronto iyo digir, iyo transformations kale oo badan oo la mid ah. sifooyinka diode noocan oo kale ah sida waxqabadka, oo xuduudaheedu xasiloonida, awoodda isgoosyada pn waajib kuma aha in ay soo bandhigaan isaga si kasta oo looga baahan yahay gaar ah.

qalab noocan oo kale ah ayaa ah xuduudaheedu korontada qaarkood iyo sifooyinka of dioska- ah:

- danab weeraryahanka at sheegay in qiimaha hadda (qaaday qiimaha celcelis ahaan) ;

- beddeli hadda at qiimaha a Siiyey danab dambe iyo heerkulka (qiimaha celcelis ahaan) ;

- qiyamka Ilodanimada inayan ugu badnaan danab dambe la ogolaan karo ee ah;

- qiimaha celcelis ahaan hadda weeraryahanka;

- qiyamka inta jeer ee aan hab hoos;

- iska caabin ah.

diode Rectifier waxaa inta badan loo soo gaabiyo si fudud loo yaqaan rectifier ah. Sida qayb ka mid ah Bannaanka, waxa uu leeyahay iska caabin sare inay hadda ah oo barwaaqaysan in hal jiho oo si hoose wixii dhacdaa jihada dambe. Taasina waxay keentaa in sixitaan hadda.

In qalab sida rectifier diode a, a ku filan yar kala duwan oo soo noqnoqoshada. inta jeer Operating loo isticmaalo warshadaha qalab noocan oo kale ah la AC in DC diinta waa 50 Hz. Yaree inta jeer ee waxaa loo arkaa inay wax ka badan 20 Khz.

kooxo dhowr diode Rectifier sida qalabka elektaroonikada ah waxa loo qaybin karaa sida ay qiimaha celcelis ahaan hadda ugu badan si toos ah. Tani diode hooseeyo xoog (0.3 amps), awood dhexdhexaad ah (ka 0.3 A 10 A) iyo waajibaadka culus (awood) dioska- rectifier (in ka badan toban amperes).

Beegyada uu ugu waaweyn ee qalabka elektarooniga ah sida sida diode rectifier ah, oo waa inay ku jiraan kala duwan u hawlgasho Heerkulka ah (sida caadiga ah u dhaxeysa -50 in +130 degrees Celsius for diode ugu badan ee nooca - Silicon) iyo heerkulka jidhka ugu badnaan (noocyo kala duwan oo xuduudaheedu, ku xiran tahay awoodda magacaabidda iyo soo saaraha).
