METHOD AND APPARATUS FOR TRANSMISSION OF ELECTRICAL ENERGY (EMBODIMENTS)

The invention relates to electrical engineering, specifically to methods and apparatuses for wireless transmission of electrical energy using resonant half-wave techniques between stationary objects, and between fixed power sources and mobile devices that receive electrical energy. The technical result of the invention is to develop wireless methods and apparatuses for charging electrical energy accumulators in stationary or mobile electrical consumers, which have uniform magnetic flux intensity over the active area of a transmitting module, high efficiency of transmission of energy, and low radiation levels. The technical result is achieved by way of including into transmission of electrical energy from a source to an accumulator, controlled by frequency of the converter of source current, of transmitting and receiving modules connected to each other by magnetic resonance coupling, and a current converter that converts a higher-frequency current format to the current required for the operation of the accumulator in the receiving module, wherein the magnetic resonance winding of the transmitting module is made in the form of a flat spiral of two wires wound from center to periphery, the magnetic resonance winding of the receiving module is made in the form of flat single- or double-wire spiral, standing waves of current and potential with a current antinode at the periphery of the winding are excited in the magnetic resonance winding of the transmitting module, energy is transmitted between the transmitting and the receiving modules. The terminals at the core of the double-wire spiral winding of the transmitting module are mutually isolated. Provided are 6 embodiments of charging apparatuses and 6 embodiments of charging methods.
