RESONANCE SYSTEM OF WIRELESS ENERGY TRANSMISSION WITH USING OF THE ELECTRIC FIELD

The paper reviews the existing types of wireless technologies for power transmission using electromagnetic interaction. According to the type of interaction, systems using magnetic, electric and electromagnetic components are distinguished. Short-range, medium-range and long-range systems are distinguished by range. As promising for implementation in future unmanned systems, the work considers a modified system of wireless transmission of electrical energy using an electric field. The scheme is presented and the principle of operation of such a system is considered. The characteristics of resonant circuits used as emitters and receivers in such a system were studied. The results of measuring the parameters of the spatial distribution of the electric field of the resonators are presented. The interaction of the spectral components of the input signal and the resonant characteristics of the radiating circuits was investigated. The paper presents the method of determining the efficiency of electric energy transmission at high frequencies and the results of measurement of transmission efficiency for the studied type of systems. It was concluded that there is an active factor in the form of an alternating electric field, the feature of which propagation allows creating a device suitable for powering unmanned mobile systems of low and medium power.
