RECTIFYING CIRCUIT FOR HIGH-FREQUENCY POWER SUPPLY

摘要

A rectifying circuit for high-frequency power supply that rectifies an alternating voltage at a high frequency exceeding 2 MHz, the rectifying circuit for high-frequency power supply including a bridge rectifier circuit that rectifies the alternating voltage inputted from a reception antenna for power transmission, a matching functional circuit that matches a resonance condition to that of the reception antenna for power transmission, and a smoothing functional circuit that smooths the voltage rectified by the bridge rectifier circuit into a direct voltage, in which the rectifying circuit for high-frequency power supply causes the bridge rectifier circuit to perform partial resonant switching in a switching operation at the time of rectification by using the matching functional circuit and the smoothing functional circuit.
