  • Publication number: 20250006415
    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.

  • Patent number: 11437915
    Abstract: A converter includes a first end, a second end, a first side and a second side switching circuits and a transformer. The first end includes a first positive terminal and a first negative terminal. The second end includes a second positive terminal and a second negative terminal. The first side switching circuit is coupled to the first end and includes a first bridge arm and a second bridge arm. Two terminals of the first bridge arm are coupled to the first positive terminal and the first negative terminal respectively. Two terminals of the second bridge arm are coupled to the first positive terminal and the second positive terminal respectively. The transformer includes a first side winding coupled to the first side switching circuit and a second side winding coupled to the second side switching circuit. The turns ratio of the first side winding and the second side winding is N:1.

  • Publication number: 20220131469
    Abstract: A power converter module includes a multilayer printed circuit board, a switching device, a controlling device and a capacitor device. The switching device includes two switching circuit combinations. Each of the switching circuit combinations includes two switching circuits connected in parallel. Each of the switching circuits includes a switching unit. The controlling device is configured for outputting a first control signal and a second control signal to control the switching circuits of the first switching circuit combination and the switching circuits of the second switching circuit combination respectively. The first control signal and the second control signal are out of phase with each other. On a direction, the switching units of the first switching circuit combinations and the switching units of the second switching circuit combinations are alternately arranged, each of a plurality of capacitors of the capacitor device is neighboring to the two adjacent switching units.
