PROBLEM TO BE SOLVED: To provide an inexpensive inverter device with a high power factor. SOLUTION: A pair of switching elements 31, 32 connected in forward series and to be turned on and off alternately are provided. A flywheel diode 41 or 42 to be connected in reverse/parallel with each switching element 31 or 32 is provided. A filter capacitor 10 to be connected at a location striding the whole of a pair switching devices 31, 32 is provided. A rectified power source 20 to be obtained by rectifying the voltage of alternating current power source 21 is provided. An oscillating inductor 60 which applies the voltage of the rectified power source 20 through one switching device 31 is provided. An oscillator capacitor 50 to be connected at a location striding the whole of an arbitrary one switching element 31 (32) and the oscillator inductor 60 is provide. An alternating current load 71 to which power is fed by receiving the voltage of the oscillator inductor 60 is provided. |
