RECTIFYING CIRCUIT FOR HIGH-FREQUENCY POWER SUPPLY

摘要

Disclosed is a rectifying circuit for high-frequency power supply that rectifies an alternating voltage at a high frequency equal to or higher than 2 MHz, the rectifying circuit for high-frequency power supply including a class E rectifier circuit that rectifies the alternating voltage inputted from a reception antenna for power transmission 10, a resonant circuit that causes the class E rectifier circuit to perform resonant switching in a switching operation at the time of rectification, a matching functional circuit that has a function of matching a resonance condition to that of the reception antenna for power transmission 10, and a function of matching the resonance condition to that of the resonant circuit, and a smoothing functional circuit that smooths the voltage rectified by the class E rectifier circuit into a direct voltage.
