Abstract:
1. A high-frequency power source device comprising: a DC power source; two switching element groups connected in parallel, one parallel connection terminal of a first of the two switching element groups being connected to a positive terminal of the DC power source, one parallel connection terminal of a second of the two switching element groups being connected to a negative terminal of the DC power source, the switching element groups being turned on and off cyclically; a first inductance element that is connected between another parallel connection terminal of the first switching element group and another parallel connection terminal of the second switching element group; a second inductance element that is connected to a connection terminal between the switching element groups and the first inductance element, and is serially connected between the switching element groups and a load; and a first capacitor that is connected in parallel with the load, wherein an output frequency that is n times as large as an oscillation frequency of the switching element groups is supplied to the load, n being an integer equal to or larger than 2.
