Abstract:
Provided is an apparatus for controlling a surge voltage. An embodiment configures a snubber coil and a snubber rectifier on a secondary side circuit in series to control a high spike surge voltage across a rectifier on the secondary side. When the rectifier is turned-off, the snubber rectifier is turned-on for a predetermined time to control the surge voltage.
