Abstract:
1. A power semiconductor device, comprising: an inverter composed of a first switching part and a second switching part interposed in series between a first power source line through which a first voltage is applied and a second power source line through which a second voltage is applied, the first and second switching parts operating complementarily; and a first control circuit and a second control circuit that control switching operations of said first and second switching parts respectively, said first and second switching parts and said first and second control circuits being combined into a module, wherein said first switching part includes a first IGBT and a first MOSFET, said first IGBT and said first MOSFET each having one main electrode connected to said first power source line and an opposite main electrode connected to an output node of said inverter, said second switching part includes a second IGBT and a second MOSFET, said second IGBT and said second MOSFET each having one main electrode connected to said second power source line and an opposite main electrode connected to said output node of said inverter, in a planar layout showing a planar arrangement of respective components within said power semiconductor device, said first control circuit is arranged to face said first switching part, one of said first IGBT and said first MOSFET is arranged near said first control circuit, and the other of said first IGBT and said first MOSFET is arranged in a position farther from said first control circuit than a transistor near said first control circuit, said second control circuit is arranged to face said second switching part, one of said second IGBT and said second MOSFET is arranged near said second control circuit, and the other of said second IGBT and said second MOSFET is arranged in a position farther from said second control circuit than the transistor near said second control circuit, the transistor being one of said first IGBT and said first MOSFET and arranged near said first control circuit applies a gate control signal from said first control circuit to a gate of the transistor arranged far from said first control circuit, the transistor being one of said second IGBT and said second MOSFET and arranged near said second control circuit applies a gate control signal from said second control circuit to a gate of the transistor arranged far from said second control circuit, a gate control signal is applied from said first control circuit via a resistive element to a gate of a transistor being one of said first IGBT and said first MOSFET, and a gate control signal is applied from said second control circuit via a resistive element to a gate of a transistor being one of said second IGBT and said second MOSFET.
