摘要
电能经过变换 ,特别是整流后 ,产生谐波及无功功率 ,造成功率因数低 ,使电网电压电流波形发生畸变 .高功率因数整流器的提出 ,可较好地解决这一问题 .本文主要综述了高功率因数整流器的拓扑结构、工作方式、优缺点和控制策略 .
In a AC/DC conversion circuit with phase control or diode rectifying, the harmonics and the reactive power are generated. So the power factor is low and harmonics distortion on the voltage and current becomes serious. A high power rectifier can be used to improve the power factor and reduce the distortion. In this paper, its topologies, operating modes, merits, drawbacks and control strategies are reviewed, and some suggestions for the development are proposed.
