Electronic circuit with a reverse-conducting IGBT and gate driver circuit
Abstract:
An electronic circuit includes a reverse-conducting IGBT and a driver circuit. A first diode emitter efficiency of the reverse-conducting IGBT at a first off-state gate voltage differs from a second diode emitter efficiency at a second off-state gate voltage. A driver terminal of the driver circuit is electrically coupled to a gate terminal of the reverse-conducting IGBT. In a first state the driver circuit supplies an on-state gate voltage at the driver terminal. In a second state the driver circuit supplies the first off-state gate voltage, and in a third state the driver circuit supplies the second off-state gate voltage at the driver terminal. The reverse-conducting IGBT may be operated in different modes such that, for example, overall losses may be reduced.
