Abstract
A control circuit is configured to adjust a phase difference which is a delay of the phase of each of the second drive signals to the phase of each of the first drive signals to a set value within a prescribed range to adjust the magnitude of output power. The control circuit includes an estimator and a setter. The estimator estimates whether an initial mode which is an operation mode of an inverter circuit in the case of a variable capacitance circuit being disabled is a leading phase mode or a lagging phase mode while the variable capacitance circuit is operating. The setter sets the prescribed range in accordance with the initial mode estimated by the estimator.
