摘　　要：本文分析了BLDCM及复合型PWM整流器的基本原理,将复合型PWM整流器与BLDCM相结合构成双PWM控制系统,以减小谐波电流对电网的影响。建立了相应的数学模型,采用转速电流双闭环控制策略,通过Simulink搭建仿真模型进行仿真分析,验证了分析的正确性。The basic principle of BLDCM and the rectifier are analyzed. The double PWM control system is composed of the rectifier and BLDCM to reduce the influence of harmonic current on power grid. The corresponding mathematical model is established, and the double closed-loop control strategy of speed and current is adopted. The simulation model is built by Simulink to verify the correctness of the analysis.
