Abstract:
A circuit performs a method for controlling turn-off of a semiconductor switching element. The method includes determining at least one operating parameter for the semiconductor switching element during an operating cycle and determining a gate discharge current based on the at least one operating parameter. The method further includes supplying the gate discharge current to a gate of the semiconductor switching element during a subsequent operating cycle to turn off the semiconductor switching element.
