Title:
POWER TRANSMISSION DEVICE, HIGH-FREQUENCY POWER SUPPLY, AND HIGH-FREQUENCY RECTIFICATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/126111
Kind Code:
A1
Abstract:
The present invention is provided with: a transmission-side AC/AC converter (1) provided with an input circuit (11) into which a commercial alternating current in inputted, and which offsets the commercial alternating current in the positive voltage direction by a voltage of half the voltage amplitude of the commercial alternating current, and an inverter (12) which converts the power that has been offset by the input circuit (11), to power having a higher frequency than the frequency of the commercial alternating current; a resonant transmission antenna (2) for transmitting the power that has been converted by the inverter (12); a resonant reception antenna (3) for receiving the power transmitted by the resonant transmission antenna (2); and a reception-side AC/AC converter (4) provided with a full-wave rectification circuit (42) which subjects the power received by the resonant reception antenna (3) to full-wave rectification, and an output circuit (43) which offsets, in the negative voltage direction by a voltage of half the voltage amplitude of the commercial alternating current, the power that has been subjected to full-wave rectification by the full-wave rectification circuit (42).
