Abstract
A power converter module includes power transistors and a substrate having a first surface and a second surface that opposes the first surface. A thermal pad is situated on the second surface of the substrate, and the thermal pad is configured to be thermally coupled to a heat sink. The power converter module also includes a control module mounted on a first surface of the substrate. The control module also includes control IC chips coupled to the power transistors. A first control IC chip controls a first switching level of the power converter module and a second control IC chip controls a second switching level of the power converter module. Shielding planes overlay the substrate. A first shielding plane is situated between the thermal pad and the first control IC chip and a second shielding plane is situated between the thermal pad and a second control IC chip.
