Abstract:
A drive circuit drives switches that are connected to each other in parallel. The drive circuit includes individual discharge paths, a common discharge path, blocking units, a discharge switch, off-holding switches, and a drive control unit. The drive control unit selects, as target switches to be driven to be turned on, at least two switches among the switches. The at least two switches include a first switch and a second switch. The first switch is last to be switched to an off-state among the at least two switches that are selected as the target switches and switched to an on-state. The second switch is other than the first switch among the at least two switches. The off-holding switches includes a first off-holding switch and a second off-holding switch. After switching the second off-holding switch to an on-state, the drive control unit switches the discharge switch to an on-state.
