Abstract:
This paper proposes a method to minimize the overall output current ripple of an interleaved-switched inverter with several half bridge branches per phase. Therefore, two types of temporal shift between the carrier signals of different branches and phases are defined. In order to get the smallest possible overall current ripple, a dynamic variation of these two temporal shifts is investigated.
