Method and device of electric energy transfer (versions)

FIELD: electricity. SUBSTANCE: transfer of electric energy is carried out by transfer of resonant oscillations of higher frequency in a circuit made of a frequency converter, a step-up resonant transformer, a single-wire line of power transmission and a step-down high-frequency transformer. The frequency converter has a voltage feedback to maintain the output voltage value in the power transmission line at a constant level that complies with the maximum load, and a frequency feedback for synchronisation of a driving oscillator with a resonant frequency of the output transformer and a power transmission line. There are other versions to transmit electric energy with the second frequency feedback to synchronise the driving oscillator with the resonant frequency of the output resonant circuit and the power transmission line, and also with the third frequency feedback to stabilise voltage in a load. EFFECT: increased efficiency factor, extended distances of electric energy transmission from a source of energy to a consumer, reduced consumption of non-ferrous metals and increased stability of transmitted voltage regardless of the load. 8 cl, 4 dwg
