摘要： A heat sink for cooling an electronic component includes a substrate comprising an electrically non-conductive material and an inlet port and an outlet port extending outward from the substrate. The inlet and outlet ports are fluidically coupled to a fluid flow surface of the heat sink by passages that extend through a portion of the substrate. The heat sink also includes a shield comprising an electrically conductive material. The shield is disposed atop or within the substrate and is configured to suppress electromagnetic interference generated by an electronic component coupled to the heat sink.

摘要： A multi-level DC-DC converter includes an input side to receive a DC power having an input voltage and current, an output side to provide power to a load at a desired output voltage and current, and a plurality of tranformer-isolated DC-DC converters connected between the input and output sides, with the tranformer-isolated DC-DC converters being connected in series on one side and connected in parallel on another side. Each of the tranformer isolated DC-DC converters further includes a power transformer having a primary winding and a secondary winding, and a plurality of switching devices each selectively operable in one of an On state and an Off state. Operating the switching devices in a complementary On state and Off state alternately at a controlled switching frequency provides for engaging the tranformer isolated DC-DC converter and operating the switching devices in a simultaneously On state bypasses the transformer isolated DC-DC converter.
