Abstract

A power device supply includes an inverter, a converter, and a cooling system. The inverter is configured to convert direct electrical current into alternating electrical current. The converter has an inductor and is configured to amplify voltage. The cooling system has top, bottom, and intermediate cooling plates. The cooling system is arranged such that the inverter and inductor are interleaved with the plates and such that the inverter and inductor are disposed on opposing sides of the intermediate cooling plate.

Claims
