Abstract:
A gate driving circuit for a voltage-driven power semiconductor switching device has (a) the voltage-driven power semiconductor switching device, (b) a driving circuit for supplying a drive signal to the gate electrode of the switching device, and (c) an inductance between the emitter control terminal or source control terminal of the switching device and the emitter main terminal or source main terminal of a semiconductor module. A voltage produced across the inductance is detected. The gate-driving voltage or gate drive resistance is made variable based on the detected value.
