Abstract
An electronics assembly includes a motor controller electronics arrangement with a solid-state switch array, a feeder cable connected to the motor controller and in electrical communication with the solid-state switch array, and a phase change material body. The phase change material body is thermally coupled to the feeder cable and arranged outside of the motor controller to limit conduction of heat generated by resistive heating of the feeder cable into the motor controller and through the feeder cable. Vehicles, electrical systems, and methods of cooling feeder cables in motor controller electronics arrangements are also described.
