  • Patent number: 10304615
    Abstract: A method of forming a power module located on a conductive substrate by providing power conversion circuitry. The method of providing the power conversion circuitry includes forming a magnetic device by placing a magnetic core proximate a conductive substrate with a surface thereof facing a conductive substrate, and placing a conductive clip proximate a surface of the magnetic core. The method of forming the magnetic device also includes electrically coupling ends of the conductive clip to the conductive substrate to cooperatively form a winding therewith about the magnetic core. The method of providing the power conversion circuitry also includes providing at least one switch on the conductive substrate. The method of forming the power module also includes depositing an encapsulant about the power conversion circuitry.

  • Patent number: 8528190
    Abstract: A method of manufacturing a power module on a substrate. In one embodiment, the method includes providing power conversion circuitry including providing a magnetic device having a magnetic core and at least one switch on the substrate. The method also includes placing a shielding structure with a baffle over the magnetic core to create a chamber thereabout. The method also includes depositing an encapsulant about the power conversion circuitry. The shielding structure limits the encapsulant entering the chamber and the baffle directs the encapsulant away from the magnetic core thereby limiting an amount of the encapsulant that contacts the magnetic core within the chamber.
