AUTOMATIC MATCHING CIRCUIT FOR HIGH FREQUENCY RECTIFICATION CIRCUIT
First Claim
1. An automatic matching circuit for high frequency rectification circuit, automatic matching circuit comprising:
- a variable inductor disposed in order to perform impedance matching at a high frequency equal to or higher than 2 MHz between an output impedance of a reception antenna for power transmission and an input impedance of a high frequency rectification circuit, to cause an inductance value to be variable by using an electronic part that electrically performs contact switching including continuous contact switching;
a variable capacitor disposed in order to perform said impedance matching, to cause a capacitance value to be variable by using an electronic part that electrically performs contact switching including continuous contact switching; and
a variable control circuit to control the electronic parts, said variable inductor and said variable capacitor, each of which electrically performs the contact switching including the continuous contact switching, in such a way as to perform said impedance matching.
