Claim Text:
1. A method of driving a power switch device, the method comprising: applying a first voltage to a gate electrode of a power switch device, the first voltage being higher than a drive voltage of the power switch device in a turn-on state; and applying the drive voltage to the gate electrode of the power switch device after applying the first voltage to the gate electrode of the power switch device, wherein the applying the first voltage includes turning on a first transistor connected between the gate electrode of the power switch device and a first power source configured to supply the first voltage, the applying the drive voltage includes turning on a third transistor without a dead time between an on state of the first transistor and an on state of the third transistor, the third transistor is connected between the gate electrode of the power switch device and a second power source configured to supply the second voltage, a second transistor is connected to the power switch device, a blocking diode is connected between the second power source and the third transistor, and the blocking diode is configured to reduce a shoot through phenomenon during a simultaneous turning off of the first transistor and turning on of the third transistor.
