ELECTRIC POWER TRANSMISSION SYSTEM
First Claim
1. An electric power transmission system, comprising:
- a power transmission antenna that constitutes a series resonator with an inductance component of L1 and a capacitance component of C1, and to which AC power is input;
a power receiving antenna that constitutes a series resonator with an inductance component of L2 and a capacitance component of C2, and which receives electromagnetic energy from the power transmission antenna via electromagnetic fields;
a rectifying unit that rectifies an output of the power receiving antenna to output DC power; and
a load to which an output of the rectifying unit is input, whereinat times including when a coupling coefficient between the power transmission antenna and the power receiving antenna is k, if a load resistance value is R, the following relationships are established;
