Abstract
A power module for operating an electric vehicle drive, comprising power switches for generating an output current based on an input current; control electronics for controlling the power switches including a first region, to which a first electric potential is applied, and a second region, to which a second electric potential is applied, wherein the second electric potential is higher than the first electric potential; a heatsink for discharging heat generated by the power switches and the control electronics; a shielding layer for electrically shielding the control electronics placed between the heatsink and the control electronics, such that the control electronics lies on the shielding layer, and the shielding layer lies on the heatsink; wherein the shielding layer is designed to connect the heatsink thermally and electrically to the first region, and thermally to the second region, and electrically insulate it therefrom.
