METHOD AND DEVICE FOR WIRELESS CHARGING OF ELECTRIC ENERGY STORAGE UNIT OF FIXED OR MOBILE ELECTRIC CONSUMER Russian patent published in 2019 - IPC H02J50/20 H02J7/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular, to methods and devices for wireless transmission of electric energy using resonant half-wave technologies between stationary objects, as well as between stationary feed devices and mobile units receiving electric power. Technical result is achieved due to inclusion in transmission of electric energy from source to drive of frequency-controlled current converter of source, transmitting and receiving modules, connected to each other by a magnetic resonant coupling and a current converter from the high-frequency current format into a format required for operation of the accumulator in the receiving module, wherein magnetic conductor winding of transmitting module is made in form of flat spiral with two-wire winding from center to periphery, magnetic resonance winding of receiving module is made in form of flat single-wire or double-wire spiral, exciting standing waves of current and potential with current antinode at periphery of winding are excited in magnetic resonance winding of transmitting module; energy transfer between transmitting and receiving modules is arranged. Outputs in the central part of two-wire spiral winding of the transmitting module are isolated from each other. There are 6 versions of charging devices and 6 versions of charging methods.

EFFECT: creation of wireless methods and charging devices of electric energy accumulator of fixed or mobile electric consumer, having uniform intensity of magnetic flux on active area of transmitting module, high efficiency of energy transfer, low level of radiation.
