Umehluko Obalulekile kanye Nezicelo
Ama-rectifier ayizingxenye ezibalulekile kumasekethe ahlukahlukene kagesi kanye nezinhlelo zokuphakelwa kwamandla. Aguqula i-alternating current (AC) ibe yi-direct current (DC), enikeza amandla adingekayo kumadivayisi amaningi kanye nezinhlelo zokusebenza. Phakathi kwezinhlobo ezahlukene zama-rectifier, ama-pulse rectifier kanye nama-polarity reverse rectifier aphawuleka ngezici zawo ezihlukile kanye nezinhlelo zokusebenza. Lesi sihloko sihlola umehluko phakathi kwalezi zinhlobo ezimbili zama-rectifier, izimiso zazo zokusebenza, izinzuzo, ukubi, kanye nezinhlelo zokusebenza.
Ama-Pulse Rectifiers
Ama-rectifier e-pulse, aziwa nangokuthi ama-rectifier e-pulsed noma ama-rectifier alawulwayo, amadivayisi aguqula i-AC ibe yi-DC ngokusebenzisa amadivayisi e-semiconductor alawulwayo njenge-thyristors noma ama-rectifier alawulwa yi-silicon (ama-SCR). Lawa ma-rectifier avame ukusetshenziswa ezinhlelweni zokusebenza ezidinga ukulawulwa okunembile phezu kwe-voltage yokukhipha kanye nogesi.
Isimiso Sokusebenza
Ukusebenza kwe-pulse rectifier kuhilela ukulawula i-phase angle ye-input AC voltage. Ngokulungisa i-triggering angle yama-SCR, i-output DC voltage ingalawulwa. Uma i-SCR ivuselelwa, ivumela i-current ukuthi idlule kuze kube yilapho umjikelezo we-AC ufinyelela ku-zero, lapho i-SCR ivala khona. Le nqubo iphindaphinda umjikelezo ngamunye wesigamu se-AC input, ikhiqiza i-pulsating DC output.
