Resonance apparatus, power transmission apparatus, and power transmission method

A microwave-rectifying circuit for rectifying AC power is equipped with: an input line into which AC power is inputted; multiple branch lines which branch off from the branching point on the output side of the input line into n lines; rectifiers which rectify the AC power flowing through the branch lines and are positioned in each of the multiple branch lines; and phase shift units which are provided upstream from the rectifier in at least n&#x2212;1 branch lines among the multiple branch lines, and shift the phase of the AC power in a manner such that relative to the AC power which flows through one branch line and arrives at the corresponding rectifier, the AC power which flows through each of the other n&#x2212;1 branch lines and arrives at the corresponding rectifier exhibits a phase difference of k&#xd7;180/n&#xb0;.

Microwave-rectifying circuit

Other resonators similar in shape to itself, with a partially open structure of a closed curve line, arranged opposite itself. A closed-curve line is formed between the resonator, which uses electromagnetic coupling to transfer high-frequency power in a non-contact manner, and the drive unit causes the resonator to rotate in the circumferential direction of the resonator in the plane of the Transfer of high-frequency power between a resonator and another resonator at multiple locations where the angles in the circumferential direction are different from each other and transmitted from one resonator to the other that is detected at each position of the resonator. Control to set the angle at which this transfer of high-frequency power is carried out based on the power value of the high-frequency power that was set. A resonance device comprising a part.
