通过纹波的直接再注入减少PWM驱动器直流线路中纹波的方法

Harmonic Reduction in DC Line of a PWM Drive by Direct Reinjection

本文介绍了一种可用来代替变流器直流侧无源与有源滤波的方法。直流侧纹波消除电路是基于直流线路中纹波的直接再注入原理而设计。

This paper introduces a solution to ripple reduction in DC line of a PWM drive.The circuits of dc-side ripple reduction are based on direct reinjection of the ripple in series with the dc line.
