Title:
RECTIFYING CIRCUIT FOR HIGH-FREQUENCY POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2015/072015
Kind Code:
A1
Abstract:
This rectifying circuit for a high-frequency power supply rectifies AC voltage at high frequencies surpassing 2 MHz and is provided with: a bridge rectifying circuit that rectifies AC voltage that is input from a resonant receiving antenna (10); a matching function circuit that matches a resonance condition between resonant receiving antennas (10); and a smoothing function circuit that smoothes voltage that is rectified by the bridge rectifying circuit into DC voltage. Partial resonant switching of a switching operation on the occasion of rectification by the bridge rectifying circuit is carried out by the matching function circuit and the smoothing function circuit.
