First Claim
1. A power conversion system, comprising:
- a power converter, comprising;
at least two circuits, wherein each of the at least two circuits comprises;
two or more phase legs, wherein each of the two or more phase legs comprises at least two semiconductor switches;
an interphase reactor configured to operatively couple one of the two or more phase legs to at least one other phase leg in the two or more phase legs;
a controller configured to;
obtain a switching pattern for each of the at least two semiconductor switches corresponding to the at least two circuits; and
selectively switch each of the at least two semiconductor switches based on the obtained switching pattern to reduce a common mode signal in the power conversion system.

Abstract
A power conversion system is presented. The power conversion system includes a power converter. The power converter includes at least two circuits, where each of the at least two circuits includes two or more phase legs, where each of the two or more phase legs includes at least two semiconductor switches. Also, the at least two circuits includes an interphase reactor configured to couple one of the two or more phase legs to at least one other phase leg in the two or more phase legs. Moreover, the power conversion system includes a controller configured to obtain a switching pattern for each of the at least two semiconductor switches of the at least two circuits and selectively switch each of the at least two semiconductor switches based on the obtained switching pattern to reduce a common mode signal in the power conversion system. Method for power conversion is also presented.
