Patent ID: 8300443

Claim:
A three-phase inverter for use with a DC power source having a positive terminal, a negative terminal, and a neutral terminal, comprising: a power semiconductor module that includes: a package; a first IGBT in the package, the first IGBT having a collector and an emitter, the collector of the first IGBT being connected to the positive terminal of the DC power source; a first diode in the package, the first diode having a cathode that is connected to the collector of the first IGBT and having an anode that is connected to the emitter of the first IGBT; a second IGBT in the package, the second IGTBT having a collector and an emitter, the emitter of the second IGBT being connected to the negative terminal of the DC power source and the collector of the second IGBT being connected to the emitter of the first IGBT at an intermediate connection point; a second diode in the package, the second diode having a cathode that is connected to the collector of the second IGBT and having an anode that is connected to the emitter of the second IGBT; and a semiconductor AC switch in the package, the semiconductor AC switch being connected between the neutral terminal of the DC power source and the intermediate connection point of the first and second IGBTs.
