Title: Power inverter module with reduced inductance

Abstract

A power inverter module includes a base module having a plurality of electrically conductive layers, including a first conductive layer, a second conductive layer and a third conductive layer. A first terminal is operatively connected to the first conductive layer at a first end and a second terminal is operatively connected to the second conductive layer at the first end. An isolation sheet is sandwiched between the first and second terminals. The first terminal and the second terminal include a respective proximal portion composed of a first material and a respective distal portion composed of a second material. At least one of the first terminal and the second terminal is bent to create an overlap zone such that a gap between the first terminal and the second terminal in the overlap zone is less than a threshold distance. The power inverter module is configured to reduce parasitic inductance.
