Abstract
A control system includes a switch circuit configured to switch an alternating-current voltage, a power transmission antenna configured to wirelessly transmit power based on the alternating-current voltage determined by switching of the switch circuit, a power reception antenna configured to wirelessly receive the power wirelessly transmitted from the power transmission antenna, a rectification circuit configured to rectify a voltage output from the power reception antenna to apply the alternating-current voltage to a load unit, a current detection unit configured to detect an alternating current flowing through the switch circuit, and a control unit configured to control a value of the alternating-current voltage applied to the switch circuit based on a value of the alternating current detected by the current detection unit.
