Electric power converter for, e.g. generator motor for motor vehicle e.g. passenger car, has low side MOSFETs and high side MOSFETs that are mounted on main surface of substrate, where substrate is made of aluminum material

摘要

The electric power converter (1) has the bridge circuit comprising the low side N-channel MOSFETs (3a,3c,3e,3g,3i,3k) and high side N-channel MOSFETs (3b,3d,3f,3h,3j,3m), where the converter is connected with a armature. The low side MOSFETs and high side MOSFETs are mounted on the main surface of a metal substrate (5), where the substrate is made of aluminum material.
