ABSTRACT:
A circuit is presented for coupling a storage capacitor to a capacitor shorting switch whereby voltage across the shorting switch is maintained at a reduced potential relative to the storage capacitor so that the voltage and potential current at the switch contacts is maintained at levels wherein it is impossible for the release of sufficient energy into the surrounding atmosphere to cause ignition of a flammable mixture of gas and air. This is accomplished by coupling the storage capacitor to the switching device via a variable voltage divider network controlled by an SCR with a zener diode controlled gate circuit and a varistor.
