Zusammenfassung:An apparatus includes a plurality of parallel-connected semiconductor switches (e.g., wide bandgap transistors) and a plurality of driver circuits having outputs configured to be coupled to control terminals of respective ones of the plurality of semiconductor switches and configured to drive the parallel-connected semiconductor switches responsive to a common switch state control signal. The apparatus further includes a control circuit configured to sense respective states of respective ones of the parallel-connected semiconductor switches and to control respective ones of the driver circuits responsive to respective ones of the sensed states.
