Abstract

A switching circuit protection technique includes detecting the self-firing of at least one switching element due to an over-voltage in a switching circuit having multiple parallel circuits, applying a firing pulse to all switching elements and the switching circuit in response to the detected self-firing and firing all of the switching elements at the same time in response to a firing pulse.
