基于SIMULINK的BUCK型PFC装置仿真

Simulation of Buck-PFC Device Based on Simulink

借鉴“整体电路”的概念 ,在完成整流滤波的同时 ,实现三相功率因数校正的功能 .对最普遍三相六开关BU CK型电路拓扑结构进行仿真 ,讨论和分析了该类型电路的控制策略 ,并给出仿真曲线 .结果表明

By using the concept of total circuit, power factor correction is accomplished along with rectification and filtering. The topology of a general three phase BUCK circuit with 6 switches is simulated, and the control strategy discussed. The simulation curves are presented, showing agreement with a theoretical analysis.
