PURPOSE:To equalize the frequency vs. output characteristics of a power source by providing a plurality of primary coils of the output transformer of an inverter corresponding to a plurality of secondary coils, superposing the primary coils and the secondary coils and disposing the primary coils in parallel with each other. CONSTITUTION:In an output transformer 10, 3 primary coils 14, 15, 16 are provided corresponding at 1:1 to the 3 secondary coils 11, 12, 13, disposed in parallel with each other, and the corresponding secondary coils 11, 12, 13 are disposed in series directly above the primary coils 14, 15, 16. The coils 11, 12, 13 are uniformly coupled to the coils 14, 15, 16. A control circuit 30 for controlling the output transistor 20 has current detecting means 31, voltage converter 32, a V/F converter 33, a transistor 34 and a pulse transformer 35. |
