资料介绍

给出了三相电压型PWM整流器在三相静止坐标系和两相同步旋转坐标系下的数学模型.选择固定开关频率的直接电流控制策略,采用电压外环和电流内环双闭环控制结构,按此方法给出了电压和电流PI调节器设计的方法,同时给出了交流侧电感和直流侧电容取值的设计.在MATLAB的SIMULINK环境下建立系统的仿真模型,仿真结果验证了主电路参数设计的正确性.

Abstract. The mathematic model of three-phase voltage-source PWM rectifier was given in three-phase sta-tionary coordinate system and two phase synchronization coordinate system. The direct current controlstrategy and the control structure of voltage outer loop and current inner loop were chosen. The designmethod of voltage and current loop PI controller were given, and the calculation of AC inductor and DC ca-pacitor were also presented. Simulation model was established in MATLAB/SIMULINK environment andsimulation results verify the correctness of the main circuit parameters.
