Control system and method of controlling control system

A control system, comprising:

• 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;
• 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;
• a clock generation circuit configured to generate a clock signal;
• a first driving circuit configured to drive the switch circuit based on the clock signal generated by the clock generation circuit;
• a transmission circuit configured to generate a signal based on the clock signal generated by the clock generation circuit;
• a transmission antenna configured to wirelessly transmit the signal;
• a reception antenna configured to wirelessly receive the signal wirelessly transmitted from the transmission antenna;
• a reception circuit configured to restore the clock signal based on the signal received by the reception antenna;
• and
• a second driving circuit configured to drive the rectification circuit based on the clock signal restored by the reception circuit.
