Abstract
A gate driver includes a first transistor and a second transistor connected in series between a first and a second power supply line, connection nodes thereof are output nodes of the gate driver, the first and second transistors being configured to operate in a complementary manner, a power supply circuit for applying an offset voltage to a source of the transistor, and a switching circuit for performing switching control to apply the offset voltage output from the power supply circuit to the source of the transistor or to apply the second potential to the source of the transistor. The switching circuit is configured to switch so as to apply the offset voltage to the source of the transistor in accordance with a timing of turning off the gate of the transistor and to apply the second potential to the source in accordance with a timing of turning on the gate.
