A FC soft-switching converter (250) includes a free-wheel circuit (22c) that includes a free-wheel diode (D6). In a second series-connected body of an auxiliary circuit (22b), an anode of a diode (D2) is connected to the connecting portion of a snubber capacitor (C2) and a diode (D3) of a first series-connected body. Further, a cathode of the diode (D2) is connected to an electrode of a first end portion of a second switching element (S2). Also, an electrode of a second end portion of the second switching element (S2) is connected to a connecting portion of the free-wheel diode (D6) and a coil (L2). |
