Integrated direct liquid cooled (DLC) power module with enhanced reliability for HEV/EV is developed.

Al DLC structure gives rise to 40% reduction of weight and cost, and 50% reduction of junction to heat sink thermal resistance.

Die lead bonding is proposed for interconnection to reduce parasitics by 50%. Advanced die and terminal attach technologies are suggested.

The predicted lifetime of the DLC module is qualified for HEV/EV application.
