Original Abstract Submitted
A high-frequency power supply apparatus includes a first power supply, a second power supply, a matching circuit, and a low-pass filter. The first power supply outputs a high-frequency voltage with a first fundamental frequency toward a load. The second power supply outputs, toward the load, a negative polarity voltage with a second fundamental frequency lower than the first fundamental frequency. The matching circuit is connected between the first power supply and the load. The matching circuit matches impedance on a side of the first power supply and impedance on a side of the load. The low-pass filter is connected between the second power supply and the load. The first power supply performs frequency modulation control by: performing frequency-modulation on the high-frequency voltage with a trapezoidal modulation signal whose frequency is equal to the second fundamental frequency, and outputting a modulated wave obtained by the frequency-modulation on the high-frequency voltage.
