摘要
分析了常用的无源和有源功率因数校正原理和方法,提出了用逆变电源负载端并联单相全桥整流器来实现功率因数校正的方法。功率因数校正器采用频率固定的PI控制,实现了在各种非线性负载下降低电流谐波含量,提高功率因数的目的。
The general theories and approaches of reactive and active power factor correction are analyzed. Then the paper introduces a new method that gives a typical shunt single-phase rectifier to correct power factor, which is controlled by PI of constant-frequency. As a result, it reduces the content of harmonic current and improves the power factor with a group of nonlinear loads.
