circuit for feeding in electricity from renewables in a coil and

摘要

The present invention relates to a power supply circuit of a coil, in particular of a coil or reel nmr of the sample, comprising two portions of the power supply line or of transmission, each connected to one of the two ends of this coil, said line portions forming with said coil an oscillating circuit or the first oscillating circuit having a resonance frequency déterminée.circuit characterized in that the two portions of the line (3, 3 ′) each comprise at least two conductors (5, 5 ′, 5 ", 5 '"), one (5, 5 ′) is connected to the coil (2), and between them have identical structures and the lengths of the conductors connected to the same, this common length is substantially a multiple of half the wavelength of resonance of the oscillating circuit (4), in that the conductors (5, 5 ′) connected to the coil (2) to one of their ends are connected together at their other end by a tuning circuit or component symmetrical adjustable (6) completing this oscillating circuit (4), and in that said oscillating circuit (4) with a symmetrical structure is supplied by a primary power supply circuit (7) by means of a transfer of energy by magnetic coupling, capacitive or magneto - capacitive of the primary power supply circuit (7) with at least one of the two conductors (5, 5 ′) connected to the coil (2) and the tuning circuit or component (6).
