ABSTRACT:
A circuit device connected between a driving circuit for an active control component such as an IGBT or MOSFET includes a capacitor which compensates for drops in the power supply voltage to the driving circuit and a voltage limiting cut-off device which cuts-off power to the driving circuit when the power supply voltage drop continues for a period long enough to cause a drop in voltage across the capacitor.
