Abstract:
A switching circuit may be provided with: a parallel circuit including a first IGBT and a second IGBT connected in parallel; a controller configured to receive a signal indicating a turn-on timing and a turn-off timing. The controller is configured to: turn on both of the first and second IGBTs at the turn-on timing, execute a first control in which one of the first and second IGBTs is turned off before the turn-off timing and the other of the first and second IGBTs is turned off at the turn-off timing in a case where current flowing through the parallel circuit is equal to or lower than a threshold value, and execute a second control in which both of the first and second IGBTs are turned off at the turn-off timing in a case where the current flowing through the parallel circuit is higher than the threshold value.
