变频器对电机性能的影响及其对策

Influence of inverter on induction motor and countermeasures

目前广泛使用的变频器都会产生不同程度的高次谐波和dv/dt问题。为此 ,本文着重分析了高次谐波和dv/dt对异步电动机性能的影响 。

The inverter will produce harmonic and dv/vt,so this paper analyses that their effect on performance of induction motor and presents some methods for solving problems.
