摘要
本文阐述PWM交流变频器电流波形失真的种类,着重以日本春日电机KVFS系列变频器为例,分析KVFS变频器电流波形严重失真的原因,并指出PWM模式与电流波形的密切关系。
The types of current wave distortion in a PWM inverter have mainly been discussed in the paper. Particularly, the inverters of KVFS series. KASUGA Electric Co. Ltd. Japan have been taken as examples to analyze the causes of serious current wave distortion in the inverters. The close relationship between the PWM pattern and the current wave has also been presented.
