摘要
介绍了基于Boost拓扑的功率因数校正技术原理、升压电感的计算,给出了双重Boost PFC的控制方案,设计了一种双重Boost PFC系统。交错式双重PFC,可以大大减小因高频开关引起的电压、电流纹波的输出,降低电感、功率管的电流应力以及滤波器的体积。
A double power factor correction system based on Boost topology was introduced. The principle of power factor correction technology, the capactitance calculation of the Boost inductor, correction control method were given.For the interleaved double PFC, the output of the voltage and current ripple, the current stress of the inductor, the power switch and the size of filter could be greatly reduced.
