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 exceeding 2 MHz, said rectifying circuit for high-frequency power supply comprising:
- a voltage doubler rectifier circuit that rectifies said alternating voltage inputted from a reception antenna for power transmission;
a partial resonance circuit that causes said voltage 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 resonance circuit; and
a smoothing functional circuit that smooths the voltage rectified by said voltage doubler rectifier circuit into a direct voltage.
