  • Publication number: 20230073768
    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.

  • Patent number: 8797003
    Abstract: In power conversion according to the three-phase converter, symmetrical component voltage values of a balanced system are calculated from wye-phase voltages on the three-phase AC input side of the three-phase converter. On the DC output side thereof, the power factor is set, an average active power value is calculated from an output voltage value and an output current value, and an average reactive power is calculated from the set power factor. On the basis of the symmetrical component voltage values, the average active power, and the active reactive power, a compensation signal for compensating for unbalanced voltages of the three-phase AC voltages and a control signal for controlling the power factor are generated, and according to the compensation signal and the control signal, a control signal for outputting DC is generated.
