三相电压型低谐波PWM整流器主电路参数间的关系

三相电压型低谐波PWM整流器主电路的多个参数之间的关系较为复杂，在仿真和实验中，若给出的参数不合理，则变换器不能正常工作，从而给仿真和实验带来一定困难。文章在考虑了输入电阻的情况下，给出了功率因数角为任意值时，主电路各参数和控制参数间的稳态关系及一些参数的约束关系。上述关系对于分析和设计被研究电路具有很好的指导意义，文中的公式通过了仿真验证。

Relations between Mains Parameters of Three-phase Voltage-type Low-harmonic PWM Rectifier

This paper presents the relations between mains parameters and constrain conditions of three-phase voltage-type low-harmonic PWM rectifier with specified power factor angle,on condition that the input resistors of the converters is not ignored. Since the relations between the parameters are very complex, unreasonable parameters will result in functional disorder of the converter, and cause difficulty during the simulations and experiments. The relations given by this paper is very helpful when analyzing and designing of the converters. Simulations are performed to verify the validity of the equations.
