Abstract
A power device driving apparatus drives a plurality of power devices including first and second power devices. In the apparatus, a plurality of drive circuits are separately provided for at least the first power device and the second power device and output drive signals to the respective power devices. The isolated power supply includes a first isolated power supply unit that supplies a first supply voltage, and a second isolated power supply unit that supplies a second supply voltage that is different from the first supply voltage. The plurality of drive circuits includes a first drive circuit that uses the first supply voltage supplied from the first isolated power supply unit to output the drive signal to the first power device, and a second drive circuit that uses the second supply voltage supplied from the second isolated power supply unit to output the drive signal to the second power device.
