  • Patent number: 10374599
    Abstract: A delay-time correction circuit delays an input signal for generating a pre-drive signal to a drive unit generating a drive signal. A transition-change sensor senses a transition change in one of a turn-on operation and turn-off operation. A correction-signal generator generates a correction signal in response to the transition change sensed by the transition-change sensor and to the input signal. A delay output unit generates an output signal corresponding to the pre-drive signal by delaying the input signal using the correction signal. The delay output unit delays the output signal that instructs the other of a turn-on operation and turn-off operation, from the input signal, in accordance with a length of a period for the transition change in the one of a turn-on operation and turn-off operation that is performed immediately before the other of a turn-on operation and turn-off operation.
