为了实现 PWM 整流器的高效运行，保护良好的动态特性，主电路参数的确定较为关键，但目前现有的选取方法存在一定的盲目性。根据三相电压型 PWM 整流器主电路结构的数学模型，提出了满足稳态电路指标以及抑制谐波电流的电感值的计算方法，该方法兼顾了交流侧电感跟踪和滤波的两种特性；为满足直流电压跟踪效果以及确保控制系统的电压外环抗扰性能，结合系统瞬态过程的分析提出了直流侧电容选取的方法，从而解决了 PWM 整流器主电路参数选取的盲目性问题。通过仿真验证了电感值和直流电容参数确定方法的有效性。

The determination for the main circuit parameters of the three - phase PWM rectifier is the key part in im-plementing the efficient operation of the PWM rectifier and keeping its good dynamic characteristics. But there is cer-tain blindness about the existing selecting methods. In this paper,an inductance value calculation method was pro-posed according to the mathematical model of the main circuit structure of the three - phase voltage type PWM rectifi-er,which could satisfy steady - state performances and restrain the inductance value of the harmonic current. The method considered both the ac - side inductance tracking and the filtering features. Besides,in combination with the analysis of the system transient process,a dc - side capacitor selection method was put forward to meet the dc voltage tracking effect and ensure the anti - interference characteristics of the control system voltage loop,which could solve the blindness in the selection of the main circuit parameters. The simulation and experimental results verified the ef-fectiveness of the proposed methods.
