Bus bar assembly for use with a compact power conversion assembly

Abstract

An electronic converter assembly comprising a first heat sink member having at least a first mounting surface and a length dimension, a plurality of power switching device modules wherein each module includes at least four separate power switching devices, the modules mounted to the first sink mounting surface such that the switching devices are aligned along the length of the sink member, each switching device including inter-converter connection terminals linkable to at least one of a load and a source and intra-converter connection terminals linkable, each intra-converter connection terminal linkable to at least one of a positive and a negative DC bus, first, second and third bus bars, each bus bar linked to the inter-converter connection terminals of at least first and second pairs of the power switching devices where the at least first and second pairs of power switching devices linked to specific ones of the bus bars are from different switching device modules and a linkage assembly including a plurality of conductors that link the intra-converter connection terminals of the power switching devices to form a power conversion topology.
