摘要：

This paper discusses a modulation control for an indirect matrix converter connects with a reactor free boost converter for induction motor drives. The square wave modulation is proposed to apply with a four-step commutation pattern to improve the voltage transfer ratio of the indirect matrix converter from 0.866 to 0.97 (VTR=v(out)/v(in)). Furthermore, a feed-forward control is proposed to apply in the reactor free boost converter to reduce the ripple in the battery current which is caused by the fluctuations at the neutral point voltage. In the experiment results, the battery current is reduced by approximately 72 % by the feed forward control. The loss analysis shows an efficiency of 94 % for the proposed method.
