Abstract: A method for forming a power module package includes providing a power module including an electrical element and an electrical connection portion; providing an electrical connection terminal including a connection end, an extension portion and an end cap, wherein the extension portion is extended between the connection end and the end cap and has a hollow cavity therein; disposing the electrical connection terminal on the electrical connection portion for electrically connecting the connection end to a corresponding electrical connection portion; packaging the power module and the electrical connection terminal through an encapsulant to form a packaged body; removing a portion of a surface of the packaged body for exposing the end cap of the electrical connection terminal; and removing the end cap to expose the hollow cavity of the electrical connection terminal, so as to form the power module package.

Abstract: A power module assembly is disposed on a substrate and dissipates heat generated through the substrate. The power module assembly includes a circuit board, a heat-generating device, a first metal block, a first filling material and a second filling material. The circuit board includes at least one plane. The heat-generating device is disposed on the plane. The first metal block includes a first side and a second side. The first side of the first metal block faces the heat-generating device, and the second side of the first metal block faces the substrate. The first filling material is disposed between the first side of the first metal block and the heat-generating device. The second filling material is disposed between the second side of the first metal block and the substrate.

Abstract: A magnetic device includes a magnetic core assembly, a first winding and a second winding. The magnetic core assembly includes a top surface, a bottom surface, a first lateral side, a second lateral side, a third lateral side, a fourth lateral side, a middle leg and two lateral legs. A first winding groove is defined by the middle leg and one lateral leg. A second winding groove is defined by the middle leg and the other lateral leg. Two opposite ends of the first winding groove are respectively exposed to the first lateral side and the fourth lateral side. Two opposite ends of the second winding groove are respectively exposed to the second lateral side and the third lateral side. At least a part of the first winding is disposed within the first winding groove. At least a part of the second winding is disposed within the second winding groove.

Abstract: The present disclosure provides a power conversion module including a magnetic component and a power device layer. The magnetic component includes a main body layer, a first magnetic core, a second magnetic core and a conductor. The main body layer includes a first surface and a second surface opposite to each other. The first magnetic core is embedded in the main body layer and adjacent to the first surface. The second magnetic core is embedded in the main body layer and adjacent to the second surface. The first magnetic core and the second magnetic core are connected to form plural magnetic columns. The conductor is embedded between the first surface and the second surface. The conductor is partially disposed between the plural magnetic columns. The power device layer is disposed on the first surface. The power device layer includes a power device electrically connected to conductor.
