Abstract

A circuit for turning off a power semiconductor switch includes a turn-off transistor coupled to switch a signal for turning off the power semiconductor switch onto a control terminal of the power semiconductor switch and a feedback control loop for controlling a voltage on the control terminal of the power semiconductor switch during turn-off. The feedback loop includes a feedback path to feedback a measurement of the voltage of the control terminal of the power semiconductor switch, a control terminal reference voltage generator to generate a time-dependent reference voltage, an error amplifier to generate an error signal representative of a difference between the voltage of the control terminal and the time-dependent reference voltage, and a forward path to convey the error signal forward for controlling the switching of the signal for turning off the power semiconductor switch onto the control terminal of the power semiconductor switch by the turn-off transistor.
