摘要
提出了一种新颖的无源功率因数校正电路,该电路在传统的无源功率因数校正基础上增加了一个简单的辅助电路,通过增大整流桥的导通角,从而降低了奇次谐波成分并消除了偶次谐波。
A novel passive power factor correction circuil is presented. It adds an additional circuit based on the traditional passive power factor corrector. By increasing conduct time of the rectifier devices the PIF and the THD can be improved. The circuil performance was verified by the simulation and experiment.
