PURPOSE:To facilitate the current balance of inverters by forming an output transformer of a plurality of primary windings connected with the output terminals of inverters at both ends and the secondary windings connected with a load. CONSTITUTION:An inverter device 16 has a power source 7, both inverters 10, 13 and an output transformer 14, and supplies from the secondary winding 14b of the transformer 14 to a load 15. The both inverters 10, 13 are formed in bridge shape as shown at transistors 8a-8d, 11a-11d, and the primary windings 14a1, 14a2 of the transformer 14 are connected. Flywheel diodes 9a-9d, 12a-12d are provided in parallel with the transistors 8a-8d, 11a-11d. Thus, the transistors 8a, 8d, 11a, 11d and 8b, 8c, 11b, 11c are alternately conducted to obtain outputs, and circulating currents due to the displacement of the conduction decreases by the induced voltage of the leakage inductance. |
