Abstract
A control circuit () is configured to detect the impedance Pof a load () and control each of the reactance value Lof a first variable reactance element (), the reactance value Lof a second variable reactance element (), and the phase shift amount φ of a phase shifter () on the basis of the detected impedance P. Consequently, impedance matching can be achieved even with the phase shifter () that performs discrete phase shift control.
