三相PWM整流器交流侧电感的设计

摘要

The effect by the state of three-phase switch on the AC side phase current is analyzed,and the design method for AC side inductor under this effect is explored.The effect and the design method are based on the model of three-phase pulse width modulation(PWM) rectifier described by switching function.The lower limit value of the inductance designed under current ripple requirement is important.The feasibility is verified by simulation and experiment.%在开关函数描述三相脉宽调制(PWM)整流器模型的基础上,分析了交流侧某相电流受三相开关状态的影响,探讨了在该影响下交流侧电感的设计方法.其中电感参数设计量的下限值,即根据纹波要求所确定的电感值对工程实际尤为重要.通过仿真及实验验证了该方法的可行性.
