Abstract: A power electronics module (PEM) is constructed to convert electricity from an input form to an output form. Electrical power conversion subcircuits having input and output ports are positioned proximal to a front mounting plate. Rigid conductor elements having respective preformed shapes are constructed to electrically interconnect the subcircuits at input and output ports thereof to form a power conversion circuit selected from among multiple power conversion circuits configurable solely by selection of the conductor elements. Other preformed conductor shapes are constructed to interconnect input and output ports of the selected power conversion circuit to ports disposed on a rear mounting plate. A controller is mechanically coupled to the front mounting plate and constructed to operate the semiconductor switches in a prescribed timing that converts the electricity of the input form to the electricity of the output form by the selected power conversion circuit.

Abstract: We describe a power converter cooling arrangement in which a base has a top plate of a thermally conductive material, and a bottom plate and side walls define a chamber. An inlet and outlet are in fluid communication with the chamber, and the chamber is flooded with a cooling fluid that flows between the inlet and outlet. A PCB of a power converter is mounted to, and thermally coupled with, the top plate, where the PCB receives a plurality of power modules (that are used in the power conversion). The base comprises a plurality of fluid channels for flowing cooling fluid therethrough. Each of the fluid channels is arranged to coincide with a location of one or more components mounted to the PCB.
