PROBLEM TO BE SOLVED: To provide a converter controller to prevent breakdown of an auxiliary switch comprising an auxiliary circuit of a soft-switching converter. SOLUTION: An 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 diode D3 of a first series-connected body and a snubber capacitor C2. A cathode of the diode D2 is connected to an electrode at one end of a second switching element S2. An electrode at the other end of the second switching element S2 is connected to the connecting portion of a coil L2 and the free-wheel diode D6. COPYRIGHT: (C)2011,JPO&INPIT
