US Patent 11276622 Inverter arrangement

A semiconductor arrangement and an inverter incorporating the semiconductor arrangement, in particular to an inverter for use with traction power units e.g. for on and off road vehicles and stationary power inversion, are described. In the arrangement, semiconductor devices are thermally and electrically coupled to a heatsink as a module. The heatsink is configured as a bus bar to electrically connect the one or more semiconductor devices together to transmit power between the one or more semiconductor devices. The semiconductor devices may be cooled using the structure to which they are attached, and also immersed in a cooling medium to further increase the cooling of the device.
