ABSTRACT:
An apparatus for cooling a switching circuit for an electric vehicle, wherein the switching circuit has at least two switching elements connected in series, includes first and second heat sinks, each having two thermally-conductive planar members forming a passage therebetween for channeling cooling fluid, an inlet port in communication with the passage, and an outlet port in communication with the passage, and a substrate for mounting at least one switching element to each of the first and second heat sinks. An ac terminal connects the switching element attached to the first heat sink in series with the switching element attached to the second heat sink, and inlet and outlet manifolds, coupled to the inlet and outlet ports of the first and second heat sinks, circulate cooling fluid through the passages of the first and second heat sinks to cool the switching elements.
