Zusammenfassung:PROBLEM TO BE SOLVED: To prevent circuit scale from being expanded or the number of switching objects from being increased in the case where a step-down/step-up chopper circuit is provided at a second coil side so as to perform bidirectional power transmission from one of a first coil and the second coil of a transformer to the other coil and from the other coil to the one coil.SOLUTION: A first capacitor Ci is connected to a first coil w1 of a transformer T via a first full bridge circuit FB1, and a second capacitor Co is connected to a second coil w2 via a second full bridge circuit FB2. A leakage inductor of the transformer T makes the connections equivalent with providing an inductor 12 between the first full bridge circuit FB1 and the second full bridge circuit FB2.
