摘要:A power output driver circuit that converts a DC voltage into an AC voltageincludes a gate driver circuit for turning on electronic switching devices. The gate drivercircuit allows for a rapid turn-off of the conducting electronic switching device by having afirst conduction path for the gate drive signals that turn-on the switching devices and asecond 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 thegate circuit shunts the stored charge directly to the source terminal of the switchingdevice.
