  • Patent number: 7205875
    Abstract: An inductor includes an elongate magnetic core, a coil wrapped around the core and a spacer that separates the coil from the core to provide a coolant passage between the coil and the core. The coolant passage may include an air passage that extends substantially parallel to an axis of the core and that has first and second openings proximate respective first and second ends of the core. The coil may include a twisted bundle of individually insulated conductors. The inductor may be housed in a flux-tolerant compartment, i.e., a conductive aluminum structure that supports eddy currents with relatively acceptable resistive losses.
    Type: Grant

  • Publication number: 20050265002
    Abstract: An integrated power module includes a longitudinally extending mounting member defining a cooling passageway on a first side thereof. A heat sink is positioned in the cooling passageway. A printed circuit board is positioned proximate a second side of the mounting member opposite the first side. A heat generating power circuit is electrically coupled to the printed circuit board and positioned between the printed circuit board and the mounting member. The power circuit is thermally coupled to the heat sink. An inductor is mounted in the cooling passageway. Methods of forming an integrated power module are also provided.
