Power is fed from a feeding coil to a receiving coil by magnetic resonance. A drive circuit outputs an IN signal generated by an oscillator as a DR signal to alternately turn ON/OFF switching transistors at a resonance frequency, whereby AC current is fed to the feeding coil, and then the AC current is fed from the feeding coil to the receiving coil. An enable signal generation circuit generates an EN signal at a frequency lower than the resonance frequency. The drive circuit outputs the DR signal only while the EN signal assumes a high level. Transmission power from a wireless feeder to a wireless receiver is controlled by adjusting the duty ratio of the EN signal.

A wireless power feeder 116 feeds power by wireless from a feeding coil L 2 to a receiving coil L 3 using a magnetic field resonance phenomenon. A power transmission control circuit 200 supplies AC power at a drive frequency fo to the feeding coil L 2, thereby making the feeding coil L 2 feed the AC power to the receiving coil L 3. A phase detection circuit 150 detects the phase difference between the voltage phase and current phase of the AC power. Concretely, the phase detection circuit compares a first detection time period during which a signal T 2 assumes a high level and a second detection time period during which a signal S 2 assumes a high level and detects the length of the time period in which the first and second detection periods overlap each other to detect the phase difference.

An electrical charging system (ECS) to electrically charge a battery includes a power transmitter, an energy coupling arrangement, at least one electrical signal shaping device (ESSD) including a controller, and an alignment means. The arrangement includes a first transducer disposed external to the vehicle and a second transducer attached with the vehicle. The alignment means communicates with the vehicle to ensure repeatable vehicle positioning so that the second transducer is positioned relative to the first transducer so that the second transducer receives the energy produced by the power transmitter wirelessly transmitted from the first transducer. The energy received by the second transducer is electrically shaped by the ESSD and further electrically transmitted through the ESSD as controlled by the controller to electrically charge the ESD. Methods to operate and electrically transmit energy through the ECS to electrically charge the EDS are also presented.
