A power generator includes: a power generating section 101 that outputs DC energy; an oscillating section 102 that converts the DC energy into RF energy with a frequency f0; a power-transmitting antenna 107 that transmits the RF energy; a power-receiving antenna 108 that receives at least a part of the RF energy that has been transmitted by the power-transmitting antenna 107; and a transmitting-end control section 110 that matches the input impedance of the oscillating section 102 to the output impedance of the power generating section 101 by changing the input impedance of the oscillating section 102 in accordance with a variation in the output impedance of the power generating section 101. The power-transmitting antenna 107 is a series resonant circuit, and the power-receiving antenna 108 is a parallel resonant circuit. And the resonant frequencies fT and fR of the power-transmitting and power-receiving antennas 107 and 108 are both set to be equal to the frequency f0 of the RF energy. |
