提高日立主传动系统EMC能力的研究与应用

Research and Application on Improving EMC Capability of Hitachi Main Drive System

通过分析日立高性能大容量三电平双PWM变频器HIVECTOL-CNV/VSI-MH在实际应用中表现出来抗干扰能力差的弱点,从设计上提出了优化的方案。此方案不仅在生产中得到了验证,并且取得了良好的效果。

In this paper, through the analysis of poor anti-interference ability weakness of Hitachi high performance and large capacity three level dual PWM drive HIVECTOL-CNV/VSI-MH in practical application, the optimization method is proposed in this paper from the design. The scheme has been verified in production, and achieves good results.
