Txhawm rau txo qhov muaj peev xwm ntawm cov cuab yeej kev puas tsuaj vim overvoltage tawg thiab txhim kho kev ntseeg tau ntawm cov khoom siv rectifier, silicon avalanche rectifier tuaj yeem siv. Hauv cov cuab yeej zoo li no, thaum qhov hluav taws xob thim rov qab tshaj li qhov tso cai siab tshaj tus nqi, qhov kev sib tsoo tsis sib haum tshwm sim thoob plaws tag nrho PN kev sib tshuam. Cov cuab yeej tuaj yeem ua haujlwm nyob rau hauv high voltage thiab siab tam sim no, yog li nws muaj peev xwm tiv taus lub zog rov qab ntau zog. Thaum tsim cov cuab yeej zoo li no, nws yuav tsum muaj ob peb yam khoom tsis xws luag, tsis sib xws resistivity thiab du junction nto. Qhov chaw sib tshuam yuav tsum raug tiv thaiv kom tsis txhob muaj qhov tawg. Lub selenium rectifier muaj lub peev xwm loj los tiv thaiv overload thiab muaj peev xwm tiv taus lub zog thim rov qab.
Nyob rau hauv ob yam yooj yim rectifiers raws li high-power diodes los yog thyristors, lub high-voltage AC zog ntawm daim phiaj yog hloov dua siab tshiab rau hauv DC fais fab mov los ntawm lub rectifier. Hais txog lwm hom rectifiers yav tom ntej (ze los yog nyob deb): choppers, chopper DC / DC converters, los yog tam sim no qhov chaw inverter active rectifiers raws li cov khoom lag luam ntawm cov diodes uas tswj tsis tau. Obviously, hom tshiab ntawm rectifier technology no muaj ntau cov ntsiab lus yuav tsum tau tsim, tab sis nws muaj peev xwm qhia tau zoo, piv txwv li, nws yog loaded nyob rau hauv lub hwj chim daim phiaj nrog me me harmonic cuam tshuam thiab lub hwj chim ntawm 1.
Lub rectifier yog ib qho khoom siv rectifier, tsuas yog muab tso rau nws yog ib qho khoom siv uas hloov pauv tam sim no (AC) mus rau tam sim no ncaj qha (DC). Nws muaj ob lub luag haujlwm tseem ceeb:
Ua ntej, hloov alternating tam sim no (AC) mus rau hauv ncaj qha tam sim no (DC), thiab muab nws mus rau lub load tom qab lim, los yog mus rau lub inverter;
[1] Thib ob, muab lub zog them rau lub roj teeb. Yog li ntawd, nws kuj ua raws li lub charger tib lub sijhawm.
