Abstract

An active snubber circuit is connected to a buck converter and decreases a first surge voltage and a second surge voltage generated by the buck converter. The active snubber circuit includes a first FET switch connected to the output point of the first surge voltage and a first power storage element, a second FET switch connected to the output point of the second surge voltage and a second power storage element, an inductor connected to a connection point positioned on an output side with respect to the output point of the second surge voltage, the first and second FET switches, and an element connected to the first and second FET switches, the inductor, and ground and through which a forward current flows.
