Abstract
A power inverter assembly provides a balanced power flow to each of a plurality of electrical machines. The power inverter assembly includes at least one heat sink having a top side and a bottom side, a plurality of pairs of power semiconductor modules mounted along the top and bottom sides of a heat sink for thermal exchange with the heat sink, and a plurality of gate driver boards configured to control the supply of DC power to each of the plurality of pairs of power semiconductor modules. A first pair of semiconductor modules is symmetrically arranged relative to second and third pairs such that the arrangement of the first, second, and third pairs of power semiconductor modules forms a geometric pattern with at least one of the second and third pairs at least partially overhanging the first pair.
