Introduction

keywords： inductance PFC

Computer switching power supply is a capacitor input circuit, and the phase difference between its current and voltage will cause the loss of switching power. In this case, a PFC circuit is required to improve the power factor. There are currently two types of PFC, one is passive PFC (also called passive PFC) and active PFC (also called active PFC).
