An integrated power control assembly mounted on an axial end of a three-phase motor includes a substrate, two input busbars each of positive and negative polarities alternatively spaced apart on the substrate, a plurality of sets of paired devices, and three output busbars corresponding to the three phases of the motor, wherein a set of paired devices includes a switching semiconductor and a diode. An inner input busbar has edges adjacent to an inner input busbar of opposite polarity and an outer input busbar of opposite polarity and configured to have at least twice as many devices as the outer input busbars. One or more sets of paired devices are disposed axially on outer input busbars and on inner input busbars along the edges. An individual output busbar is disposed over and electrically coupled to one or more sets of paired devices disposed on adjacent input busbars of opposite polarity.
