摘　　要：分析了电力电子设备中纹波电流产生的原因,设计了一种新型的通过并联副回路来消除主回路电流纹波的方法,首先阐述其工作原理,并使用PSPICE工具对其仿真验证,然后通过硬件实验验证了该方法的可行性,最后对该方法进行系统分析.The reason of the generation of ripple current was analysed. A new method called parallel sub- loop device was proposed to eliminate the current ripple. How it works was explained. A simulation using PSPICE software tool was taken to simulate the model of the device. This device was demonstrated to be useful by a hardware circuit experiment. And a systematic analysis of the method was taken.
