摘要
本文介绍并分析了变频器本身和外部EMI的来源,根据EMI产生的三要素原理,重点从硬件和软件两方面对比分析了变频器EMI的抑制措施。最后对各种方法,需要注意的问题以及未来变频器EMI抑制的发展方向进行了总结和展望。
In this paper,the main sources of inverter itself and external interference are described and analyzed.According to the three theory of inverter interference,both of hardware and software are introduced and analysed comparatively about the measures of inverter interference suppression.Then EMI suppression application are enumerated. Finally.all kinds of methods and the problems needed attention in the development of inverter interference suppression are summarized and prospected.
