Classification: CPC H  G | IPC G  H

Claim 0:
1. A control system comprising:
a power transmission unit configured to wirelessly transmit alternating-current power; and
a power reception unit configured to receive the alternating-current power wirelessly transmitted from the power transmission unit,
wherein the power transmission unit comprises:
a first switching unit configured to switch the alternating-current power at a timing based on a first clock signal and wirelessly transmit the switched alternating-current power; and
a clock transmission unit configured to wirelessly transmit the first clock signal, and
wherein the power reception unit comprises:
a clock reception unit configured to receive the first clock signal wirelessly transmitted from the clock transmission unit;
a first detection unit configured to detect an amount of electric power and a switching timing of the alternating-current power wirelessly transmitted by the first switching unit;
a first clock generation unit configured to generate a second clock signal based on the switching timing detected by the first detection unit;
a first clock selection unit configured to select a clock signal based on the first or second clock signal in accordance with the amount of electric power detected by the first detection unit; and
a first rectifying unit configured to switch the alternating-current power wirelessly transmitted by the first switching unit at a timing based on the clock signal selected by the first clock selection unit.
