Abstract
A power converter includes a pair of series connected switches and circuitry. The circuitry includes another switch and an optocoupler that activates responsive to changes in current through one of the series connected switches exceeding a predefined threshold. Activation of the optocoupler causes the another switch to conduct and reduce a gate voltage of the one of the series connected switches to reduce the changes in current through the one of the series connected switches.
