摘要： An electrodynamic apparatus includes a first arm extending in a first direction, a second arm supported by the first arm, a linear actuator that moves the second arm along the first direction with respect to the first arm, a support extending in a second direction that is different from the first direction and supporting the first arm, and a rotating mechanism that rotates the support about an axis of rotation parallel to the second direction. The first arm includes a power transmission antenna. The second arm includes a power reception antenna. The power transmission antenna supplies electric power to the power reception antenna wirelessly. In rotating the support, the linear actuator moves the center of gravity of the second arm to the axis of rotation first, and then the rotating mechanism rotates the support.

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 and a second amplitude and performs control for eliminating a difference between a third amplitude of the relay alternating current power and a fourth amplitude of the relay alternating current power.

摘要： A control method for a power transmitting device is provided, the power transmitting device including a power transmitting antenna, which transmits AC power wirelessly to the power receiving antenna of a power receiving device, and an oscillator. The method includes supplying pulse signals that control first and second switching element groups to the oscillator, and changing a phase shift amount between a first pulse signal and a second pulse signal. The method also includes causing the oscillator to change the voltage of the AC power output and to set an initial value of the phase shift amount. The method further includes causing the oscillator to output preliminary AC power of a voltage to reduce the phase shift amount from the initial value, fixing the phase shift amount, and causing the oscillator to output the AC power while maintaining the voltage corresponding to the fixed phase shift amount.

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.
