1. A high-frequency power device comprising:

  • a transformer;

    a high-frequency voltage generating circuit configured to feed a high-frequency voltage to a primary coil of the transformer so that the primary coil forms an electric feeder section; and

    a divider configured to divide a voltage across opposite terminals of a secondary coil of the transformer or opposite terminals of an element of a circuit associated with the secondary coil at a predetermined voltage ratio, wherein;

    the divider is a series circuit in which a first impedance element and a second impedance element are connected in series;

    the first impedance element is an impedance element connected to a first potential side of the opposite terminals of the secondary coil of the transformer or to a first potential side of the circuit associated with the secondary coil, while the second impedance element is an impedance element connected a second potential side of to the opposite terminals of the secondary coil or to a second potential side of the circuit associated with the secondary coil, the first potential side being higher than the second potential side; and

    the first impedance element has an impedance represented by Za and the second impedance element has an impedance represented by Zp, a second equivalent capacitance to ground on the second potential side is represented by Cp, a first equivalent capacitance to ground on the first potential side is represented by Ca, and a ratio of Za/Zp is substantially equal to a ratio of Cp/Ca.
