Qhov chaw inductance muaj qhov tseem ceeb cuam tshuam ntawm lub converter kev ua tau zoo vim tias nws lub xub ntiag hloov cov tso zis voltage ntawm lub converter. Yog li ntawd, lub tso zis voltage txo raws li cov load tam sim no txo. Tsis tas li ntawd, lub input tam sim no thiab tso zis voltage waveforms hloov loj heev.

Yog li ntawd, dab tsi yog lub kaum sab xis ntawm lub rectifier?

Cov kev sib hloov Lub sij hawm thaum cov thyristors tawm mus thiab cov khoom xa tuaj yog hu ua lub sijhawm sib tshooj. Lub sij hawm angular, thaum ob qho khoom siv sib koom ua ke yog hu ua kev sib hloov lub kaum sab xis los yog sib tshooj lub kaum sab xis.

Kuj Paub, dab tsi yog tswj tag nrho rectifier? Ib theem tag nrho tswj rectifier tso cai hloov ntawm ib theem AC rau DC. Feem ntau qhov no yog siv ntau yam kev siv xws li roj teeb them, ceev tswj ntawm DC motors thiab pem hauv ntej kawg ntawm UPS (Uninterruptible Power Supply) thiab SMPS (Switched Mode Power Supply). • Tag nrho plaub lub cuab yeej siv yog thyristors.

Xav txog qhov no, dab tsi yog qhov cuam tshuam ntawm qhov impedance ntawm kev ua haujlwm ntawm converter?

Qhov no tsuas yog ua tau yog tias qhov voltage qhov chaw tsis muaj internal impedance . Cov qhov chaw impedance yog coj li purely inductive. Nws ua rau cov SCRs tawm thiab tawm los ua ke. Thaum lub sij hawm commutation lub sij hawm, qhov tso zis voltage yog sib npaug rau qhov nruab nrab tus nqi ntawm lub conducting theem voltages.

Dual converter yog dab tsi?

A dual converter yog ib qho khoom siv hluav taws xob uas muaj ob converters thiab lawv sib txuas ua ke rov qab los. Ib tug choj hloov AC rau DC uas ua haujlwm raws li lub tshuab hluav taws xob thiab lwm tus choj ib nrab hloov DC rau AC uas ua haujlwm raws li inverter. dual converter khiav lub DC lub cev muaj zog nyob rau hauv ob qho tib si kev coj nrog ceev tswj ib yam nkaus thiab.
