Abstract: A multi-stage power module is provided. The multi-stage power module may include at least one heat sink having a first surface, a second surface and an edge, a first set of switches disposed on the first surface of the heat sink, a second set of switches disposed on the second surface of the heat sink, a plurality of capacitors disposed adjacent to the edge of the heat sink, and a bus bar assembly symmetrically coupling the capacitors to each of the first set of switches and the second set of switches.
