Abstract:
A resonance-type contactless power supply adjusts a phase difference of an inverter control signal in a current cycle in a manner the same as that in a previous cycle in a case that a power parameter in the current cycle and that in the previous cycle satisfy a predetermined relationship, and adjusts the phase difference of the inverter control signal in the current cycle in a manner opposite to that in the previous cycle in a case that the power parameter in the current cycle and that in the previous cycle don't satisfy the predetermined relationship. The power parameter represents system efficiency. Thus, a suitable input current or voltage of the transmitter-side resonant circuit is determined by scanning actually, so that the system can operate at optimal efficiency.

Claim (Index 9):
The power transmitter according to  claim 8 , wherein said transmitter-side control circuit comprises:\n a second current detection circuit configured to detect an input current of said inverter circuit and to obtain a third signal representing said input current; a second voltage detection circuit configured to detect an input voltage of said inverter circuit and to obtain a fourth signal representing said input voltage; a second power calculating circuit configured to calculate said second parameter using said third signal and said fourth signal; a second wireless communication circuit configured to receive said first parameter; an efficiency tracking circuit configured to calculate said power parameter using said first parameter and said second parameter, and to adjust a compensation signal in a current cycle in a manner the same as that in a previous cycle in a case that said power parameter in said current cycle is smaller than or equal to that in said previous cycle, and to adjust said compensation signal in said current cycle in a manner opposite to that in said previous cycle in a case that said power parameter in said current cycle is larger than that in said previous cycle; and an inverter signal generating circuit configured to generate said inverter control signal in accordance with said compensation signal.
