单相Boost功率因数校正电路优化及仿真

The optimal simulation of power factor corrector based on saber

对单相Boost功率因数校正器进行了设计和仿真研究。对电路的电压环及其脉动补偿电路、输入滤波器进行了仿真研究和参数优化。脉动补偿电路及优化的电压环使输出电压纹波显著减小,并改善了电路动态性能。优化的输入滤波器在保持电路稳定的同时获得了较高的功率因数并给出了纹波几乎为零的理想输入电流,建立了一个基于saber的优化的功率因数校正电路仿真模型。

A single-phase boost chop-mode power factor corrector is designed, The simulation studies and parameter optimizations are made for the voltage loop, pulse compensation circuit and the input filter respectively. The tipple of the output voltage is decreased remarkably and the dynamic performances of the circuit are improved obviously due to the pulse compensation circuit and the optimized voltage loop. The higher power factor and the input current with △I≈0 have been obtained by using the optimized input filter while retaining the stability of the correction circuit. An optimized simulation model of power factor corrector based on the saber is presented.
