Modular inverter power electronic for intelligent e-drives

A novel design of IGBT half-bridge power-modules for automotive applications was developed. In comparison to standard modules, advantages regarding electrical, thermal and mechanical interfaces could be achieved. In the present paper, investigations regarding the general design, the increase of lifetime and robustness and advantages from the application point of view of this 'Inverter Building Block' (IBB) are described. For proving its applicability, the IBB is at first used in an integrated 2x80 kW axle-drive-unit with double-inverter and PMSM-machines.
