摘要：
In control over a contactless power supply system that includes: a power transmitting device that includes a power transmitting unit, a power supply unit supplying electric power to the power transmitting unit and a matching transformer coupled between the power supply unit and the power transmitting unit and including a variable inductor and a variable capacitor that adjust an impedance of the power transmitting device; and a power receiving device that includes a power receiving unit carrying out electromagnetic resonance with the power transmitting unit to contactlessly receive electric power from the power transmitting unit, before starting transfer of electric power from the power transmitting device to the power receiving device, the variable inductor is adjusted on the basis of an impedance of the power receiving device to thereby bring the impedance of the power transmitting device close to the impedance of the power receiving device.
