摘　　要：选择固定开关频率电流控制策略,给出了三相电压型PWM整流器的双闭环结构,按此方法确定了电压、电流PI调解器的设计方法,同时给出了交流侧电感和直流侧电容的计算方法。在MATLAB/SIMULINK环境下建立其仿真模型,仿真结果表明,该方法使主电路参数的取值范围大大缩小,且保证了系统的动态和静态性能,为实际工程中确定主电路参数和系统设计提供了可靠依据,对三相PWM整流器系统设计有实际意义。Current control with fixed switching frequency is selected. And the double closedloop of three-phase PWM rectifier is given. The PI parameters of current and voltage adjustor are designed by simplification. Meanwhile, a calculation method of inductance in AC side and capacitance in DC side is proposed. A simulation model based on MATLAB/SIMULINK is constructed and the results of the simulation are analyzed. The results show that this design method greatly reduces the range of main circuit parameter value and the system possesses better dynamic and static performance. This model provides a basis for the determination of parameters in the main circuit during an actual system design and contributed to the design of three-phase PWM rectifier in engineering.
