摘要
为降低产品输入谐波含量,提高功率因数,设计了基于FAN7529的150W临界导通模式有源功率因数校正电路,给出了电路参数设计,搭建了样机,实现了160V^264V宽电压输入,功率因数PF≥0.985,总谐波畸变因数THD<10%,效率≥93.5%,电路可靠工作。
In order to reduce products＇ input harmonic and improve power factor,this article presents a active power factor correction circuit using FAN7529, which operates in the critical conduction mode,This paper presents the circuit and establishes a sample,the ouput power of the circuit is 150W,160V～264V wide voltage range input is achieved,power factor is increased to 0.985,total harmonic distortion is reduced to 10%,efficiency is is higher than 93.5%.Moreover,the circuit is stable.
