Ib lub capacitor yog suav nrog hauv Circuit Court los ua lub lim kom txo qis ripple voltage. Xyuas kom tseeb tias koj txuas lub capacitor kom zoo hla DC tso zis terminals ntawm lub rectifier kom cov polarities phim.
Yam khoom twg lim cov ripples hauv lub voj voog rectifier Mcq?
Kev piav qhia: Kev lim dej feem ntau ua los ntawm shunting lub load nrog capacitor. Nws nyob ntawm qhov tseeb tias lub capacitor khaws lub zog thaum ua thiab xa tawm lub zog thaum tsis ua haujlwm. Thoob plaws hauv cov txheej txheem no, cov ripples raug tshem tawm.
Dab tsi lim siv nyob rau hauv lub voj voog rectifier?
Lub lim yog ib qho khoom siv tso cai hla dc tivthaiv ntawm lub nra thiab thaiv cov ac tivthaiv ntawm cov khoom tso tawm. Yog li qhov tso zis ntawm lub lim lim yuav yog qhov tsis tu ncua dc voltage. … Capacitor yog siv los thaiv dc thiab tso cai rau ac hla.
Yuav ua li cas koj nres lub rectifier los ntawm ripples?
Yog li no, txhawm rau txo cov ripples hauv lub voj voog rectifier nrog capacitor lim ${R_L}$ yuav tsum tau nce, Cov lus nkag zaus yuav tsum tau nce, thiab Capacitor nrog lub peev xwm siab yuav tsum yog siv.
Yuav ua li cas ripples tuaj yeem txo qis hauv cov zis lim?
Ripple voltage originates raws li cov zis ntawm lub rectifier los yog los ntawm tiam thiab commutation ntawm DC fais fab tuag. … Ripple tej zaum yuav yog txo los ntawm lub lim hluav taws xob, thiab tshem tawm los ntawm tus tswj hluav taws xob.
