Abstract
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 current doubler rectifier circuit that rectifies the alternating voltage inputted from a reception antenna for power transmission, a partial resonant circuit that causes the current doubler rectifier circuit to perform partial 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, and a function of matching the resonance condition to that of the partial resonant circuit, and a smoothing functional circuit that smooths the voltage rectified by the current doubler rectifier circuit into a direct voltage.
