Daga cikinPFC canza wutar lantarki, Canjin wutar lantarki da aka tsara tsarin samar da wutar lantarki abu ne mai mahimmanci.Ayyukan samar da wutar lantarki a cikin PFC bai bambanta da na yau da kullum na wutar lantarki ba, amma akwai bambanci a cikin wutar lantarki.Matsakaicin wutar lantarki na yau da kullun yana buƙatar samar da wutar lantarki mai gyara 220V, yayin da PFC ke ba da wutar lantarki ta B+PFC.

Bayan gyarawa, ba a ƙara capacitor mai tacewa, kuma ana amfani da ingantaccen ƙarfin rabin zagayen da ba a tace ba azaman wutar lantarki na chopper.Tun da tabbataccen ƙarfin lantarki na chopper an “yanke” a cikin tsarin igiyar ruwa na yanzu, halayen ƙaƙƙarfan igiyoyin su ne:
1. Ambulan na yanzu ya daina aiki, kuma ambulansa iri daya ne da na'urar wutar lantarki, kuma zangon ambulan da wutar lantarki iri daya ne.
2. Saboda tasirin saran, ƙarfin wutar lantarki na rabi na DC ya zama babban mitar (yanke yanke shawara ta hanyar yankewa, kimanin 100khz) ikon "AC".Wannan babban mitar “AC” dole ne a sake gyara shi kafin a iya daidaita shi ta hanyar amfani da wutar lantarki na PWM na gaba.
3. Daga ra'ayi na gaba ɗaya na samar da wutar lantarki na waje, tsarin wutar lantarki ya cimma cewa ƙarfin wutar lantarki na AC da AC halin yanzu suna cikin lokaci kuma ƙarfin lantarki da na yau da kullum suna cikin layi tare da sinusoidal waveform, wanda ba wai kawai warware matsalar wutar lantarki ba. amma kuma yana magance matsalolin daidaitawar wutar lantarki da tsangwama na lantarki.

Maɗaukakin ƙarfin “madaidaicin halin yanzu” ana gyara shi ta diode mai gyara kuma a tace shi cikin wutar lantarki na yanzu kai tsaye sannan a ba da shi zuwa wutar lantarki ta PWM na gaba.Wannan wutar lantarki na DC kuma ana kiranta B+PFC.Fitar wutar lantarki ta B+PFC ta chopper gabaɗaya ya fi +300V bayan ainihin 220 AC gyara da tacewa.Dalili kuwa shi ne, an zaɓi babban layin wutar lantarki, diamita na inductor ƙarami ne, kuma ƙarfin wutar lantarki ya ragu kaɗan.Ƙarfin capacitor na tace yana da ƙananan, kuma tasirin tacewa yana da kyau, kuma akwai fa'idodi da yawa kamar ƙananan buƙatu don bututun sauya PWM na ƙasa.

A halin yanzu, a cikin ɓangaren samar da wutar lantarki na PFC, bututun chopper wanda ke aiki azaman canji yana da yanayin aiki guda biyu:
1. Yanayin Gudanar da Ci gaba (CCM): Mitar aiki na bututu mai sauyawa yana dawwama, kuma yanayin aikin gudanarwa yana canzawa tare da girman ƙarfin lantarki.
2. Yanayin ƙaddamarwa na katsewa (DCM): Mitar aiki na bututu mai canzawa yana canzawa tare da girman ƙarfin yankan.

ThePFC canza wutar lantarkisashi da ɓangaren motsa jiki na PWM canza wutar lantarki a cikin wutar lantarki gyare-gyaren gyare-gyaren wutar lantarki duk an kammala su ta hanyar haɗakarwa, kuma IC guda ɗaya na iya kammala zane.
