Switch driver circuit

Switch driver circuit

A driver circuit for a semiconductor power switch. The driver circuit supplies a high voltage pulse to the gate of an IGBT. The driver circuit also monitors the voltage on the collector of the IGBT with respect to the emitter. If the voltage at the collector of the IGBT does not drop when the IGBT i...

description A driver circuit for a semiconductor power switch. The driver circuit supplies a high voltage pulse to the gate of an IGBT. The driver circuit also monitors the voltage on the collector of the IGBT with respect to the emitter. If the voltage at the collector of the IGBT does not drop when the IGBT is turned on, the IGBT driver circuit detects a short circuit and triggers a linear integrator within the driver circuit. The linear integrator gently ramps down the voltage on the gate of the IGBT.
