ABSTRACT:
A power output driver circuit that converts a DC voltage into an AC voltage includes a gate driver circuit for turning on electronic switching devices. The gate driver circuit allows for a rapid turn-off of the conducting electronic switching device by having a first conduction path for the gate drive signals that turn-on the switching devices and a second conduction path that rapidly discharges stored energy in the gate/drain capacitance of the switching devices, resulting in a faster turn-off time. A transistor in the gate circuit shunts the stored charge directly to the source terminal of the switching device.
