| 摘 要： | 由于逆变器电源对输出接地电容的限制,对严重的共模电磁干扰难以用大容量的共模滤波器抑制共模噪声。文章介绍了一种新型的基于噪声电流补偿原理的电力电子装置无源干扰抑制技术,探讨了不同方案实现对共模噪声电流的补偿,并在一台DC/AC逆变器中进行了补偿测试。实验结果证实了该EMI抑制方法的有效性。

| Abstract: | With the limitation to the ground capacitance by inverter,it is difficult to suppress the severe common-mode noise by large CM filter.This paper introduces a new method of suppressing the common-mode EMI of power electronic convert based on compensating common-mode current noise,and researches on compensating CM noise current in different ways.Be tested in DC/AC inverter,the results approved the good effect of this suppression technique. |
