Abstract
An AC-DC converter includes two series circuits, an inductor, and a common snubber circuit. Each series circuit includes a switch and a current block device. The block device blocks a current from its high potential side to its low potential side when the first device is closed and allows the current from the low potential side to the high potential side when the first device is opened. The inductor is interposed between a first connection point between the switch and the block device of one series circuit and a second connection point between the switch and the block device of the other series circuit. The common snubber circuit is connected between each of the first connection point and the second connection point and at least one of both ends of the one series circuit.
