Electroinduction wireless system of power supply of mobile agricultural electrical units

Abstract

The electro induction method for power supply of mobile units is proposed. This method is designed to transmit electrical energy to mobile unit. The description of the contactless receiving/transmitting device is presented. This device contains frequency converter, step-up high-frequency resonant transformer, energy transmission line located inside the roadbed on which the electrical unit moves, and energy receiving system for the mobile unit. The analysis of the test results of the device model sample is presented. The reactive electromagnetic field generated by the supply electroinduction system works as a translator of energy in the developed electrical energy transmission method. The application of the contactless electrical energy transmission for mobile units will permit to remove the costs of the contact circuits installation or the costs of the special drums for cable receiving, as well as to ensure high reliability and to decrease negative influence of vehicles on the environment.
