Umehluko Obalulekile kanye Nezicelo
Ama-rectifiers ayingxenye ebalulekile kumasekethe e-elekthronikhi ahlukahlukene kanye nezinhlelo zokuphakela amandla.Baguqula i-alternating current (AC) iye ku-direct current (DC), banikeze amandla adingekayo kumadivayisi amaningi nezinhlelo zokusebenza.Phakathi kwezinhlobo ezihlukene zezilungisi, izilungisi ze-pulse rectifiers ne-polarity reverse rectifiers ziphawuleka ngezici zazo ezihlukile kanye nezinhlelo zokusebenza.Lesi sihloko sidingida umehluko phakathi kwalezi zinhlobo ezimbili zezilungisi, izimiso zazo zokusebenza, izinzuzo, ukonakala, kanye nezinhlelo zokusebenza.
Ama-Pulse Rectifiers
Ama-Pulse rectifiers, awaziwa nangokuthi ama-pulsed rectifiers noma izilungisi ezilawulwayo, angamadivayisi aguqulela i-AC kuya ku-DC ngokusebenzisa amadivayisi alawulwayo we-semiconductor afana nama-thyristors noma ama-silicon-controlled rectifiers (SCRs).Lezi zilungisi zivame ukusetshenziswa ezinhlelweni ezidinga ukulawula okunembile phezu kwe-voltage ephumayo kanye neyamanje.
Isimiso Sokusebenza
Ukusebenza kwe-pulse rectifier kufaka phakathi ukulawula i-engeli yesigaba ye-voltage ye-AC yokufaka.Ngokulungisa i-engeli yokucupha yama-SCR, i-voltage ye-DC ephumayo ingalawulwa.Uma i-SCR icushiwe, ivumela okwamanje ukuthi idlule kuze kube yilapho umjikelezo we-AC ufinyelela ku-zero, lapho i-SCR ivala khona.Le nqubo iphinda uhafu womjikelezo wokokufaka kwe-AC, ikhiqize okukhiphayo kwe-DC.
Izinzuzo
Ukulawula Okunembile: Ama-Pulse rectifiers ahlinzeka ngokulawula okuhle kakhulu ku-voltage ephumayo kanye neyamanje, okuzenza zilungele izinhlelo zokusebenza ezidinga ukuphuma kwe-DC okulungiswayo.

4.Ukudluliswa kwe-HVDC: Kumasistimu okudlulisela i-high-voltage direct current (HVDC) ukuze asebenze kahle
I-polarity Reverse Rectifiers
Izilungisi ze-polarity reverse, ezaziwa nangokuthi izilungisi zokuvikela i-polarity reverse noma izilungisi zokuvikela i-voltage ehlehlayo, ziklanyelwe ukuvikela amasekhethi emonakalweni odalwe ukuxhumana okungalungile kwe-polarity.Baqinisekisa ukuthi isifunda sisebenza ngendlela efanele noma ngabe i-polarity yokunikezwa kwamandla ihlehlisiwe.
Isimiso Sokusebenza
Ingxenye eyinhloko ye-polarity reverse rectifier i-diode noma inhlanganisela yama-diode.Uma ixhunywe ochungechungeni ngokunikezwa kwamandla, i-diode ivumela i-current ukuthi igeleze ngendlela efanele kuphela.Uma i-polarity iguqulwa, i-diode ivimbela okwamanje, ivimbele ukulimala kumjikelezo.
Emiklamo ethuthuke kakhulu, ama-MOSFET (ama-metal-oxide-semiconductor field-effect transistors) asetshenziselwa ukuhlinzeka ngokwehla kwamandla kagesi ahamba phambili aphansi nokusebenza kahle okuphezulu uma kuqhathaniswa nama-diode.Lezi zilungisi ezisekelwe ku-MOSFET zilungisa ngokuzenzakalelayo ku-polarity efanele futhi ziqinisekise ukusebenza kahle kwesekethe.
Izinzuzo
Ukuvikelwa Kwesekethe: Izilungisi ze-polarity reverse zivikela ngempumelelo izingxenye ze-elekthronikhi ekulimaleni ngenxa yokuxhumeka okungalungile kwe-polarity.
Ubulula: Umklamo ulula futhi ungahlanganiswa kalula kumasekethe akhona.
Izindleko: Izilungisi ze-polarity reverse ezisuselwa ku-Diode azibizi futhi zitholakala kalula.
Ukubi
I-Voltage Drop: I-Diode-based rectifiers yethula ukwehla kwe-voltage eya phambili, okunganciphisa ukusebenza kahle kukonke kwesekethe.
Ukulawula Okunomkhawulo: Lezi zilungisi azinikezi ukulawula phezu kwe-voltage ephumayo noma yamanje, njengoba umsebenzi wazo oyinhloko uwukuvikela.
Izinhlelo zokusebenza
