Abstract
The wireless power transmission system includes a power supply device and a power receiving device. The power supply device includes a power supply coil, an inverter driving the power supply coil and a radio and a first processor. The power receiving device includes a resonant circuit wirelessly receiving electric power from the power supply coil, a rectifying circuit DB outputting a rectified voltage, a load, a radio unit and a second processor. The second processor transmits a communication packet in a predetermined period of time, the communication packet including information about a rectified voltage value and a circulation index value indicating transmission sequence. The first processor outputs a signal according to the rectified voltage value included in the communication packet every time the first processor receives the communication packet without delay.
