Abstract
A wireless power transmission/reception system includes a wireless power transmission circuit and a wireless power reception circuit. The wireless power transmission circuit includes an oscillator, a DC-AC converter that converts a direct current to an alternating current and is turned on/off in response to a control signal, a power transmission coil that transmits AC power, a signal reception coil, and a signal receiver that transfers the control signal to the DC-AC converter. The wireless power reception circuit includes a power reception coil, a rectifier that converts an alternating current to a direct current and is turned on or off in response to the control signal, an control signal generator that generates the control signal, a signal transmission coil, and a signal transmitter that transmits the control signal through the signal transmission coil.
