摘要： A relay apparatus in a wireless power transmission system includes a relay power reception antenna that receives power transmission alternating current power from a power transmission power transmission antenna, a relay rectifier that converts the power transmission alternating current power into relay direct current power, a relay inverter circuit that converts the relay direct current power into relay alternating current power, and a relay power transmission antenna that wirelessly transmits the relay alternating current power. When transmitting data to the power transmission apparatus through amplitude modulation, the relay apparatus varies amplitude of voltage of the power transmission alternating current power received by the relay power reception antenna between a first amplitude (V1) and a second amplitude (V2) and performs control for eliminating a difference between a third amplitude (V3) of the relay alternating current power, which corresponds to the first amplitude (V1), and a fourth amplitude (V4) of the relay alternating current power, which corresponds to the second amplitude (V2).

摘要： A power transmitter wirelessly transmits electric power to a power receiver that includes a reception antenna. The power transmitter includes: an inverter circuit; a transmission antenna which sends out the AC power having been output from the inverter circuit; and a control circuit which, based on measurement values of voltage and current to be input to the inverter circuit, determines a value of a control parameter defining an output voltage from the inverter circuit and controls the inverter circuit by using the determined value of the control parameter. When at least one of the measurement values of voltage and current to be input to the inverter circuit changes, the control circuit changes the value of the control parameter based on the measurement values of voltage and current so that a voltage to be output from the power receiving circuit is maintained within a predetermined range.

摘要： A wireless power feeding unit includes a power transmitting module and a power receiving module. The power transmitting module includes a first inverter circuit which is connected to a power source via a switch, a first transmission coil connected to the first inverter circuit, a second inverter circuit which is connected to the power source or another power source not via the switch, a second transmission coil which is connected to the second inverter circuit, and a power transmission control circuit which controls the first and second inverter circuits. The power receiving module includes a first reception coil opposed to the first transmission coil and a second reception coil opposed to the second transmission coil. During operation of the first and second inverter circuits, even while supply of power to the first inverter circuit is stopped, the power transmission control circuit maintains control of the second inverter circuit.

摘要： A wireless power transmission system includes a power control device, a power transmitting device, a relay device, and a power receiving device. The power control device includes a direct-current power supply, and a main control circuit that generates a first load instruction value and a second load instruction value. The power transmitting device returns a first response signal and information on alternating-current power supplied to a load circuit in the relay device ,such as a voltage value, when receiving the first load instruction value. The load circuit returns a second response signal when receiving the second load instruction value. The main control circuit determines that not the load circuit but the relay-side power receiving circuit is faulty when not receiving the second response signal within a first period and receiving the first response signal within a second period and not receiving is the information within a second period,

摘要： An electric generator includes a magnetic flux generating unit that generates a magnetic flux, a rotation unit that rotates about a rotation axis, and an induction coil unit including a winding. The magnetic flux generating unit, the rotation unit, and the induction coil unit are arranged along the rotation axis. The rotation unit is disposed between the magnetic flux generating unit and the induction coil unit. The rotation unit includes a magnetic flux changing part. The magnetic flux changing part passes across a space through which the magnetic flux linked to the winding passes, by a rotation of the rotation unit. A density of the magnetic flux linked to the winding is changed by the magnetic flux changing part passing across the space. An electromotive force is induced in the induction coil unit in accordance with the change in the density of the magnetic flux linked to the winding.
