PURPOSE: To enable the stabilized high-frequency conversion by forming a constant current high-frequency power source of a rectifying and boosting direct current power source and a high-frequency converting unit, and raising the direct current voltage in relation to a commercial power source. CONSTITUTION: A rectifying and boosting direct current power source 1 of a constant current high-frequency power source A rectifies a commercial power source Vs , and converts it to the boosted direct current voltage Ddc . A high-frequency converting unit 2 converts the voltage Vdc to the high-frequency output. Consequently, since the voltage Vdc is boosted in relation to the voltage Vs , output of the converting unit 2 can be easily set high. Lowering of the voltage due to the inductance L at a concentrated constant, which is inserted so as to stabilize load circuits B1-B4, can be thereby absorbed, and the converting unit 2 can be stably operated. |
