A power switching assembly includes a circuit board mounted on an insulating substrate, a power switching transistor having a mounting surface mounted to the circuit board and a top surface located opposite the mounting surface, and a heat sink associated with the top surface of the power switching transistor, the heat sink operating to dissipate thermal energy from the top surface of the power switching transistor. The power switching assembly forms a part of a current inverter electrically connected between a direct current power source and an alternating current motor on a vehicle. The current inverter is adapted to converts DC current into three phase AC energy.
