Title:
NON-CONTACT POWER TRANSMISSION METHOD AND NON-CONTACT POWER TRANSMISSION SYSTEM
Document Type and Number:
Japanese Patent JP2014183668
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a non-contact power transmission system that uses a balanced line for a power transmission antenna and transmits power in a non-contact manner.SOLUTION: A balanced line 3 and a high-frequency power supply device 2 for supplying power to the balanced line 3 by a high frequency wave constitute a power transmitting unit 1A, and a coil 4 for receiving power by magnetically coupling with the balanced line 3 and a load 5 for consuming the power received by the coil 4 constitute a power receiving unit 1B. The balanced line 3 transmits the high frequency wave and thereby a magnetic field is generated around conductor lines 3a, 3b of the balanced line 3. Electromotive force is induced at the coil 4 coupled with the magnetic field, and thus the power supplied to the balanced circuit 3 is transmitted to the power receiving unit 1B in a non-contact manner. The power transmitted to the power receiving unit 1B is adjusted to be maximum by an impedance adjusting circuit 21 in the high-frequency power supply device 2 and an impedance adjusting circuit 51 in the load 5.
