I-PFC (Power Factor Correction) ekunikezeni amandla ukusiza ukulungisa ubudlelwano besigaba phakathi kwamanje kanye ne-voltage, ngaleyo ndlela kuthuthukiswe isici samandla sesekhethi. Ezimweni lapho isici samandla siphansi, kungase kube nenani elikhulu lokulahlekelwa amandla asebenzayo ohlelweni, okuholela ekungasebenzini kahle. Ukwethulwa kwe-PFC inductor yokulungiswa kwezinto zamandla kusiza ukunciphisa lokhu kulahleka kwamandla asebenzayo, kuthuthukise ukusetshenziswa okusebenzayo kwamandla kagesi.
