A power module, including: a first conductor, disposed at a first reference plane; a second conductor, disposed at a second reference plane, wherein projections of the first and second conductors on the first reference plane have a first overlap area; a third conductor, disposed at a third reference plane; a plurality of first switches and a plurality of second switches, wherein at least one of the first switches and at least one of the second switches that are located on a left side are alternatively disposed, at least one of the first switches and at least one of the second switches that are located on a right side are alternately disposed, and the left side and the right side of the first overlap area are oppositely disposed. Heat sources of the power module are evenly distributed and its parasitic inductance is low.

Power module

A power module assembly is disclosed and includes a package body, a first wiring layer, a capacitor, and a system bus set. The package body includes a first surface, a second surface and two switches connected in series to form a bridge arm between the first surface and the second surface. The first wiring layer is disposed on the first surface. The capacitor is connected in parallel with the bridge arm to form a first high-frequency loop. The system bus set includes a positive-electrode bus and a negative-electrode bus fanned out from the first surface, respectively. The projection of the positive-electrode bus or/and the negative-electrode bus on the first surface is at least partially overlapped with the projection of the two switches on the first surface. The bridge arm is electrically connected between the positive-electrode bus and the negative-electrode bus to form a second high-frequency loop.
