Abstract: A power converter module includes a multilayer printed circuit board, a switching device, a magnetic core element and a winding via. The multilayer printed circuit board has a first surface, a second surface and an inside layer. The multilayer printed circuit board includes a plurality of copper layers. The magnetic core element is disposed in the inside layer and includes a hole. One end of the winding via is electrically connected to the switching device, and the other end of the winding via is electrically connected to the second surface. The winding via penetrates through the hole and forms a magnetic assembly. An amount of the copper layers on a first side of the magnetic core element close to the first surface of the multilayer printed circuit board is at least two more than a second side of the magnetic core element.

Abstract: A power converter module includes a multilayer printed circuit board, a switching device, a capacitor device, a first via, a second via, a third via and a fourth via. The multilayer printed circuit board has a first surface and a second surface and includes a plurality of copper layers including a plurality of positive copper layers and negative copper layers. The plurality of positive copper layers and the negative copper layers are disposed in staggered arrangement. The switching device is disposed on the first surface and includes a switching positive terminal and a switching negative terminal. The capacitor device is disposed on the first surface and includes a capacitor positive terminal and a capacitor negative terminal, and the capacitor device forms a capacitor area. The projections of the adjacent positive and negative copper layers and the capacitor area on the first surface at least partially overlap with each other.
