PURPOSE:To reduce a leakage self-inductance of a full-wave converter by providing double secondary winding with respect to the same primary winding, and splitting it to individually provide a commutation rectifier and a filter choke coil for each winding. CONSTITUTION:A bridge type converter has FETs 2 and 3 as switching elements, a main transformer 4 and capacitors 21 and 22. The secondary winding of the transformer 4 is wound double in number of turns as compared with a conventional one to obtain the same voltage, and split to windings 6 and 7. Rectifiers 8 and 9 are coupled to both the ends of the windings 6 and 7, and output through choke coils 10, 26 and a capacitor 11, etc. As a result, two half-wave forward output circuits are resultantly provided in parallel at the secondary side of the transformer 4 to obtain the same output voltage while reducing a leakage self-inductance.
