Magnetic field resonance system
A magnetic field resonance system is used for long-distance electrical transmission compared with other systems.A person whose name is Marine devised.
The research team to which he belongs succeeded in the experiment of non-contact electric power electrical transmission in 2007.
The system is a magnetic field resonance system.
Principle
This system uses a coil and a capacitor for a receiving side the power transmission side.A magnetic field is formed when current flows into a coil.
Vibration of the magnetic field which occurred gets across to the coil of a receiving side.
A receiving side changes it into electric power.
About efficiency
How to raise efficiency: ●Resonance phenomena are used.
●Unite the resonance frequency of a receiving side the power transmission side.
●High-frequency power is flowing in the power transmission side.
●Mainge associative strength between coils high.
Subject.
●A possibility that electromagnetic waves will leak. ●The high efficiency of a miniaturization is difficult.
●The frequency which can be used is restricted.
