Abstract
A plurality of converter circuits A and B are provided. The converter circuits A and B have circuit structures that are identical to each other. In the converter circuit A, a resonant capacitor 31, a resonant inductor 32 and a primary winding 51 of a transformer 5 are connected in series, with the two ends of the serial circuit thus achieved connected between the connecting point of switching elements 11 and 12 and one end of a source 10. The output ends of output rectifier smoothing circuits 7 and 8 are connected commonly. Resonant circuits 3 and 4 of the converter circuits A and B are connected with each other.
