Abstract
A semiconductor device includes: a parallel connection structurebetween a first node and a second node; a first snubber device and a second snubber device having a clamp level that is the same as or higher than the output voltage of a power source section. One terminal of the first snubber device is connected through the first node to one end of the parallel connection structure, the opposite terminal of the first snubber device is connected through a third node to one terminal of the second snubber device, and the opposite terminal of the second snubber device is connected through the second node to the opposite end of the parallel connection structure. Electric power is fed back to the power source section through the second and third nodes.
