3-phase SiC-automotive drive inverter system with a 1200V, 150A SiC-MOSFET-Sixpack module, an integrated gate driver, with all drive and monitoring functions including DC-link voltage, phase current and temperature sensing, and the DC-link itself in an extremely compact housing (600cm
³
). A novel, low-inductive bus bar arrangement is implemented with a total commutation inductance of less than 5nH, which allows commutations slew rates up to 40kV/ μs, extremely low switching losses and a low voltage over-shoot during turn-off.
