| Abstract: | In this paper,the inverters of KVFS series have been taken as examples to state the main control circuit of the series inverters.On the basis of it this paper analyzes the causes of serious current wave distortion in the KVFS inverters.This paper presents the close relationship between the PWM pattern and the current wave.In view of existing PWM control pattern which is usually used for the present this paper proposes the correction method accordingly. |
