Abstract
A device which enables a self-healing capacitor with more than one group of sections in series to undergo repetitive clearing without generating the resulting potential differences between the series sections which causes additional failures. In one embodiment, the device to conduct charge is a diode and resistor connected across each group of parallel sections so as to be nonconducting when the capacitor is charged but to become conducting when a clearing event occurs. An additional aspect of the device is a method for charging such a capacitor so that no section is overcharged.
