FIELD: electricity.SUBSTANCE: invention relates to the electrical engineering. The installation for contact-free energy supply according to one embodiment is represented with a resonant unit for energy transmission and resonant unit for energy receipt, which is coupled magnetically to the resonant unit for energy transmission by means of resonance in a magnetic field. Energy from the energy source is transmitted through the resonant unit for energy transmission to the resonant unit for energy receipt, at that the resonant unit for energy transmission and the resonant unit for energy are coupled magnetically by means of resonance in a magnetic field. One unit out of the resonant unit for energy transmission to the resonant unit for energy receipt is set to a certain unique resonant frequency while the other one has a set of resonant frequencies, including the preset certain unique resonant frequency.EFFECT: increasing energy transmission efficiency.10 cl, 17 dwg |
