ABSTRACT:
A method and an apparatus for resetting at least one Silicon Controlled Rectifier (SCR) in an H-bridge. The apparatus comprises a current interruption device for controlling current flow through the H-bridge, and a negative voltage detector for detecting a negative voltage at the H-bridge and driving the current interruption device to control the current flow through the H-bridge.
