Abstract
A first switching element and a gate of a voltage-driven switching element are connected by a gate turn-on wiring through a first resistor. The gate of the voltage-driven switching element and a second switching element are connected by a gate turn-off wiring through a second resistor. A charge pump unit has a first capacitor, and a second capacitor configured to output a negative voltage. A resistor unit is arranged in at least one of a first wiring configured to connect the gate turn-on wiring and the first capacitor and a second wiring configured to connect the gate turn-off wiring and the first capacitor, and is configured to charge the first capacitor through the first wiring when the first switching element is turned on and to discharge the first capacitor through the second wiring when the second switching element is turned on.
