Ib qho ntawm DC tswj fais fab mov: rectifier Circuit Court

Oct 14, 2022

Txhua lub tshuab hluav taws xob xav tau DC lub zog los muab lub zog. Vim yog tus nqi siab ntawm kev siv, cov roj teeb feem ntau tsuas yog siv hauv cov cuab yeej siv hluav taws xob tsawg. Ntawm no peb tham txog yuav ua li cas hloov AC fais fab rau hauv DC tswj fais fab mov. Cov khoom siv hluav taws xob DC dav dav yog tsim los ntawm cov khoom hauv qab no: Lub tshuab hluav taws xob rectifier hloov lub zog zaus hloov tam sim no rau hauv pulsating ncaj qha tam sim no. Lub tshuab lim lim lim tawm cov khoom siv AC hauv lub tshuab hluav taws xob DC, txo cov AC cov khoom thiab ua kom cov khoom DC nce. Lub tshuab hluav taws xob tswj hluav taws xob siv hluav taws xob tawm tswv yim tsis zoo los ua kom ruaj khov rau DC voltage rectified.

1. Ib nrab-yoj rectification Circuit Court: Ib nrab-yoj rectification yog siv cov unidirectional conductivity ntawm diodes, kom cov voltage Vo los ntawm transformer tuaj yeem ncav cuag qhov load hauv ib nrab ntawm lub voj voog.

2. Tag nrho-yoj rectifier Circuit Court: tag nrho-yoj rectifier Circuit Court muaj li ntawm lub transformer nrog ib tug nruab nrab kais nyob rau hauv lub thib ob sab thiab ob diodes, qhov zoo thiab tsis zoo ib nrab voj voog muaj tam sim no ntws los ntawm lub load, uas txhim kho cov rectification efficiency.

Ib-theem choj rectifier Circuit Court yog qhov yooj yim tshaj plaws uas hloov AC rau DC. Thaum soj ntsuam cov hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm lub rectifier Circuit Court, lub diodes nyob rau hauv lub rectifier Circuit Court muaj unidirectional conductivity. Thaum lub sij hawm zoo ib nrab voj voog, lub diodes D1 thiab D3 yog qhib, thiab qhov zoo ib nrab voj voog ntawm sine yoj yog tau ntawm lub load kuj. Thaum lub sij hawm tsis zoo ib nrab voj voog, lub diodes D2 thiab D4 tau qhib, thiab qhov tsis zoo ib nrab ntawm lub voj voog ntawm sine yoj tau txais ntawm cov khoom ua haujlwm. Qhov zoo thiab qhov tsis zoo ib nrab voj voog ntawm kev thauj khoom tsis kam yog ua ke, thiab ib txoj kev pulsating voltage nyob rau tib qho kev taw qhia tau txais.
