Ho ea kamoo re tsebang, hajoale ho na le mefuta e 'meli ea PFC, e' ngoe ke PFC e sa sebetseng (e boetse e bitsoa passive PFC), 'me e' ngoe e bitsoa phepelo ea motlakase e sebetsang.(e boetse e bitsoa PFC e sebetsang).

Passive PFC ka kakaretso e arotsoe ka "mofuta oa matšeliso a inductance" le "mofuta oa potoloho o tlatsang phula".

"Inductance compensation" ke ho fokotsa phapang pakeng tsa motlakase oa motheo le motlakase oa AC ho ntlafatsa ntlha ea matla."Inductance compensation" e kenyelletsa ho khutsa le ho se khutse, 'me matla a "puseletso ea inductance" a ka Finyella feela 0.7 ~ 0.8, eo ka kakaretso e leng haufi le high-voltage filter capacitor.

"Mofuta oa potoloho o tlatsang phula" ke oa mofuta o mocha oa potoloho ea matla a se nang letho, e tšoauoang ka ho sebelisa potoloho e tlatsang phula ka morao ho borokho ba borokho ho etsa hore sekhahla sa conduction se be se tloaelehileng sa tube ea rectifier.Leqhubu le fetoha leqhubu le haufi le leqhubu la sine, 'me matla a eketseha hoo e ka bang 0.9.Ha ho bapisoa le potoloho ea khale ea inductive passive power factor correction, melemo ke hore potoloho e bonolo, phello ea matla e bohlokoa, 'me ha ho hlokahale hore u sebelise inductor ea molumo o moholo ho potoloho ea ho kenya.

ThePFC e sebetsange entsoe ka li-inductors, li-capacitor le likarolo tsa elektroniki.E nyane ka boholo mme e sebelisa IC e inehetseng ho lokisa waveform ea hajoale ho lefella phapang ea mekhahlelo lipakeng tsa linotlolo tsa hajoale le tsa voltage.Active PFC e ka fihlela matla a phahameng, hangata ho fihla ho 98% kapa ho feta, empa litšenyehelo li phahame.Ntle le moo, PFC e sebetsang e ka boela ea sebelisoa e le phepelo ea motlakase e thusang.Ka hona, ts'ebelisong ea li-circuits tsa PFC tse sebetsang, li-standby transformer hangata ha li hlokehe, 'me Ripple ea motlakase oa DC oa PFC e sebetsang e nyane haholo, mme ntlha ena ha e hloke ho sebelisa filthara ea matla a sa feleng.
