Ngokokwazi kwethu, okwangoku kukho iindidi ezimbini ze-PFC, enye yi-PFC esebenzayo (ekwabizwa ngokuba yi-PFC esebenzayo), kwaye enye ibizwa ngokuba ngumbane osebenzayo.(ekwabizwa ngokuba yi-PFC esebenzayo).
I-Passive PFC yahlulwe ngokubanzi "uhlobo lwembuyekezo ye-inductance" kunye "nohlobo lwesekethe yokuzalisa intlambo".
"Imbuyekezo ye-Inductance" kukunciphisa umehluko wesigaba phakathi kwesiseko esikhoyo kunye ne-voltage yegalelo le-AC ukuphucula umbane wamandla."Imbuyekezo ye-inductance" iquka ukuthula kunye nokungathuli, kwaye amandla ombane "wembuyekezo ye-inductance" inokufikelela kuphela kwi-0.7 ~ 0.8, ehlala isondele kwi-high-voltage filter capacitor.
"Uhlobo lwesekethe yokuzalisa intlambo" luhlobo olutsha lwesekethe yokulungiswa kwamandla okwenziwa, ebonakaliswa ngokusebenzisa isiphaluka sokuzalisa intlambo ngasemva kwebhulorho yokulungisa ukuqhelanisa kakhulu i-angle yokuqhuba yetyhubhu yokulungisa.I-pulse iba yi-waveform ekufutshane ne-sine wave, kwaye amandla anyuka aye malunga ne-0.9.Xa kuthelekiswa ne-inductive yemveli ye-passive power factor correction circuit, i-advants kukuba i-circuit ilula, impembelelo yamandla ibalulekile, kwaye akukho mfuneko yokusebenzisa i-inductor yomthamo omkhulu kwi-input circuit.
IPFC esebenzayoyenziwe ngee-inductors, ii-capacitors, kunye namacandelo e-elektroniki.Incinci ngobukhulu kwaye isebenzisa i-IC ezinikeleyo ukulungelelanisa i-wave wave yangoku ukubuyisela umahluko wesigaba phakathi kwezitshixo zangoku kunye ne-voltage.I-PFC esebenzayo inokufezekisa amandla aphezulu, ihlala ukuya kuthi ga kwi-98% okanye ngaphezulu, kodwa ixabiso liphezulu.Ukongeza, i-PFC esebenzayo inokuphinda isetyenziswe njengobonelelo lwamandla ancedisayo.Ke ngoko, ekusetyenzisweni kweesekethe ze-PFC ezisebenzayo, iziguquli zokulinda zihlala zingafuneki, kwaye I-ripple ye-voltage ye-DC yemveliso ye-PFC esebenzayo incinci kakhulu, kwaye le nto ayifuni ukusebenzisa i-capacitor yokucoca amandla amakhulu rhoqo.
