摘要
介绍了三相功率因数校正电路几种主要的拓扑结构——三相单开关功率因数校正电路、三相两开关PFC电路、三相三开关PFC电路、三相四开关PFC电路等;并分析了每种拓扑结构的特性、优点以及缺点,应用MATLAB软件对其中部分电路做了仿真。
The paper introduces some main topologies of three- phase power factor correction circuit, such as three- phase single switch PFC circuit, three-phase two/three/four switch PFC circuit and so on. It also shows characteristics, advantages and disadvantages of each topology. Some of them are simulated by MATLAB.
