PROBLEM TO BE SOLVED: To provide a power circuit capable of realizing cost reduction and high reliability by applying the output of a multi-output control circuit to a single transistor converter for a decrease in the number of elements. SOLUTION: This power circuit is equipped with a main switch 3 connected in series with a primary winding of a transformer 2 insulated between primary side and secondary side, and includes a main switch 4 provided in addition to the main switch 3. These switches are connected with each other in parallel, and a control circuit 10 connected with control terminals of the main switches 3, 4. In the power circuit, a gate pulse may be outputted alternately to the control terminals of the main switches 3, 4 at fixed intervals from the control circuit 10. COPYRIGHT: (C)2005,JPO&NCIPI
