Three-phase magnetic field system for wireless energy transfer

摘要

In this paper a three-phase magnetic field system is studied, applied to a wireless power transfer. The research is directed not only to the distribution of the magnetic field but to optimize the energy transfer efficiency, and to reduce the electromagnetic field influence to the close environment. The development of the future intelligent transportation system depends on the electric mobility, namely, the individual or the public electric vehicles. It is crucial to achieve progress in the batteries and the battery charging, especially through a wireless power transfer technology. In this technology, the study of the magnetic field as an energy transporter is important. The main conclusions concern the alignment, the size of the coils, the spatial orientation of the magnetic field, the detachment and the tilt between the windings.
