RECTIFYING CIRCUIT FOR HIGH-FREQUENCY POWER SUPPLY
First Claim
1. A rectifying circuit for high-frequency power supply that rectifies an alternating voltage at a high frequency equal to or higher than 2 MHz, said rectifying circuit for high-frequency power supply comprising:
- a current doubler rectifier circuit that rectifies said alternating voltage inputted from a reception antenna for power transmission;
a partial resonant circuit that causes said current doubler rectifier circuit to perform partial resonant switching in a switching operation at a time of rectification;
a matching functional circuit that has a function of matching a resonance condition to that of said reception antenna for power transmission, and a function of matching the resonance condition to that of said partial resonant circuit; and
a smoothing functional circuit that smooths the voltage rectified by said current doubler rectifier circuit into a direct voltage.
