WIRELESS CHARGING SYSTEM FOR MOBILE DEVICES Russian patent published in 2014 - IPC H02J7/00 

FIELD: electricity.

SUBSTANCE: invention claims the wireless charging system for mobile devices, which includes: a multiposition charger with one or several charging cells formed by one or several structures of transmitting inductance coils and an electrical feed circuit of the transmitting coils; an energy receiver comprised of an electrical feed circuit and a receiving inductance coil, which is featured by the fact that charging cells are formed with structures of transmitting coils surrounding them at least at two sides thus providing charge and/or power supply to energy receivers placed in any three-dimensional orientation in the charging cells due to generation of an evenly distributed magnetic field; structures of the transmitting coils are placed around the charging cell so that distribution of the magnetic field is defined by the position and three-dimensional orientation of the energy receivers inside the charging cell due to secondary induced currents at metal surfaces of the energy receivers; structures of the transmitting coils are placed around the charging cell so that magnetic fields generated by currents in parts of the transmitting coil structure are subtracted from each other outside the charging cell and summed up inside the charging cell in the area of energy receivers placement.

EFFECT: potential charging of different mobile devices with low emission to the far zone.
