Abstract
A power transmitting apparatus included in the contactless power feeding apparatus includes a power supply circuit that supplies AC power having a predetermined drive frequency to a transmission coil for supplying power to a power receiving apparatus, a first coil and a first capacitor that are connected between the power supply circuit and the transmission coil, a second capacitor that is connected at first end to the first capacitor and is connected at a second end to the second end of the transmission coil, and a control circuit. Also, the power receiving apparatus includes a receiver coil for receiving power, and a resonant circuit that includes a resonance capacitor that resonates together with the receiver coil. Also, the control circuit of the power transmitting apparatus controls the power supply circuit such that the predetermined drive frequency falls within a predetermined frequency range including a resonance frequency of the resonant circuit.
