Summary. This article presents resonance system of wireless power transmission which operates at frequencies between 0.5 and 50 kHz and contains receiving and transmitting modules and a system to creation of wireless line for resonance transmission of electric energy. The system is based on a single-line resonance power transmission method developed in Russian Research Institute of Electrification of Agriculture. The system works in standing wave mode, which is characterized by a phase shift between current and voltage in time and space. This feature enables the use of wires with small cross-sections and even conductive channels in the atmosphere. A conductive channel is formed by two pulsed semiconductor lasers, a beam convergence assembly and optical lens. The laser frequencies are spaced in accordance with Fraunhofer lines of resonant absorption of beating by atmosphere components with small percentage of the atmosphere’s composition, in comparison with the total number of particles, that facilitates to minimize the expenses on the channel ionization. Selective ionization enables the exclusion of blockages of laser radiation with frequencies v1 and v2 when the components are fully ionized. A number of laser types used previously are also analyzed in this paper: the CO2 laser, the X-ray laser and the neodymium laser. It is presents two methods and devices for electrical energy transfer to vehicles moving either along an arbitrary or a prescribed path. In the former case the channel generator is positioned beside the power source, while in the latter–directly on the moving object. In the second instance, a V-shaped antenna is used as a receiver at which all the generators from the moving objects are directed.
Keywords: wireless power transmission, resonance electrical system, conducting channel.
