Research output: Contribution to journalConference articlepeer-review


In this paper a three-phase magnetic field system
is applied to the wireless power transfer system. 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 surroundings. 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. The study of the magnetic field is
important in this technology. The energy transfer efficiency
depends of the alignment, the size of the coils, the spatial
orientation of the magnetic field, the detachment and the tilt
between the windings.
