SNPC(Simplified Neutral Point Clamped) topology as a promising three-level converter topology, implementing such a topology using existing commercial power module inevitably leads to significant parasitic inductance, which restricts its further development. So it is necessary to integrate the entire topology in a single module. In this paper, a power module for the SNPC topology is designed. Specifically, through independent designs of the former stage and latter stage commutation loops, an overlapped busbar structure is introduced to reduce the difference in parasitic inductance between different phases. The proposed module design is verified through simulation and experiments.
