PROBLEM TO BE SOLVED: To provide a VHF DC-AC inverter, which can efficiently supply a plurality of outputs. SOLUTION: This DC-AC inverter is provided with a switching means 13, such as a transistor connected between a source of supply voltage +VIN and a source of reference voltage (ground potential), a first resonance waveform formation network which responds to the switching means, a first load circuit 33 which responds to the first resonance waveform formation network, a second resonance waveform formation network which responds to the switching means 13, and a second load circuit 43 which responds to the second resonance waveform formation network. The first resonance circuit includes a first capacitor connected in parallel to the switching means 13 and a series circuit of an inductance L11 and a second capacitor C12, which is inserted between the power supply-side terminal of the switching means and the load circuits 33. The second resonance circuit includes a first capacitor connected in parallel to the switching means 13 and a series circuit of an inductance L21 and a second capacitor C21 which is inserted between the switching means and the load circuit 43. |
