Classification: CPC H  G | IPC G  H

Claim 6:
7. The control system according to claim 6,
wherein the power transmission unit further comprises:
a third frequency changing unit configured to change the frequency of the first clock signal and output the resultant clock signal; and
a second switching unit configured to switch other alternating-current power at a timing based on the clock signal output from the third frequency changing unit and wirelessly transmit the switched alternating-current power, and
wherein the power reception unit further comprises:
a fourth frequency changing unit configured to change the frequency of the first clock signal output from the clock reception unit and output the resultant clock signal;
a second detection unit configured to detect an amount of electric power and a switching timing of the alternating-current power wirelessly transmitted by the second switching unit;
a second clock generation unit configured to generate a third clock signal based on the switching timing detected by the second detection unit;
a second clock selection unit configured to select the third clock signal or the clock signal output from the fourth frequency changing unit in accordance with the amount of electric power detected by the second detection unit; and
a second rectifying unit configured to switch the alternating-current power wirelessly transmitted by the second switching unit at a timing based on the clock signal selected by the second clock selection unit.
