- ELECTRONIC CIRCUIT WITH A REVERSE-CONDUCTING IGBT AND GATE DRIVER CIRCUIT

摘要

The electronic circuit includes a reverse-conducting IGBT and a driver circuit. The first diode emitter efficiency of the reverse-conducting IGBT at the first off-state gate voltage is different from the second diode emitter efficiency at the second off-state gate voltage. The driver terminal of the driver circuit is electrically connected to the gate terminal of the reverse-conducting IGBT. In the first state, the driver circuit supplies the on-state gate voltage at the driver terminal. In the second state, the driver circuit supplies the first off-state gate voltage, and in the third state, the driver circuit supplies the second off-state gate voltage at the driver terminal. The inverse-conducting IGBT can be operated in different modes, for example, so that the total losses can be reduced.
