Abstract:
A driver circuit is used for driving a plurality of switch elements connected between a power supply terminal and a common terminal. Each switch element includes an anode connected to the power supply terminal, a cathode, and a gate. The cathode is connected to a common terminal. The gate controls electrical conduction between the anode and the cathode. The driver circuit includes a switch circuit connected between the power supply terminal and the common terminal, and a driver into which a drive current flows. The switch circuit is in parallel with the switch elements, and electrically connects or disconnects the power supply terminal and the common terminal in response to a control signal supplied thereto. A transmission line, having a specific characteristic impedance, is connected between the common terminal and the driver circuit.
