Abstract
A thermal management system for an automotive inverter includes an active discharge circuit in thermal communication with a DC link capacitor, a thermal interface material positioned between the active discharge circuit and the DC link capacitor such that heat generated from the active discharge circuit is transferred to the DC link capacitor, and a coolant channel for a cooling fluid extending between the DC link capacitor and a base plate of the automotive inverter, wherein the heat generated from the active discharge circuit of the automotive inverter is transferred from the DC link capacitor to dissipate the heat. A method to thermally manage heat dissipated from automotive inverter is also provided.
