Abstract
(EN)
According to one aspect of the present invention, a driving circuit (1) is provided with a constant current control amplifier 11, a constant voltage control amplifier 12, and consumption current adjustment units 18 and 19 that respectively control the consumption currents of amplifiers. Also, a current control unit 6 individually controls the consumption current adjustment units 18 and 19 on the basis of the driving state of an IGBT4 gate.
