Abstract
The present invention controls, within a frequency range, an output command value not to exceed the upper limit of an output command permitted by a high-frequency amplifier. A method for controlling a high-frequency power supply device and the high-frequency power supply device involve performing frequency control within a frequency range of variable frequencies, limiting the upper limit of an output command value for controlling an output of a high-frequency amplifier within the frequency range of variable frequencies on the basis of an output limit value, and thereby preventing damaging of the high-frequency amplifier caused by an excessive command.
