淺述變頻空調(diào)的諧波抑制方法

摘要：本文介紹了目前變頻空調(diào)中功率因數(shù)校正的幾種方法，包括無源單電感PFC、無源帶諧振電感PFC、有源PFC、部份有源PFC等，并闡述了這幾種PFC的電路原理及其各自的優(yōu)缺點(diǎn)。 敘詞：諧波抑制 變頻空調(diào) PFC PF值 APFC Abstract：This article introduces several kinds of method for power factor correction of inverter air conditioning, including passive single inductor PFC, passive belt resonant inductance PFC, active PFC, part of an active PFC, etc, and expounds the principles and the circuit of PFC their advantages.
