multi feeding in electricity from renewables and coil and nmr spectrometer with such feeding in electricity from renewables

摘要

The present invention relates to a power supply circuit multifrequency of a coil nmr, comprising two portions of the power supply line or transmission of the main line, these portions of the main line, each comprising a portion of conductor connected to said coil, these portions are connected with said coil constituting a first oscillating circuit having a resonance frequency déterminée.circuit (1), characterized in that the portions of the power supply lines or of the main transmission (3, 3 ′) consist of the portions of the line conductors multi - to be controlled impedance, each comprising at least one other portion of conductor (6, 6 ′) is not connected to the coil (2), extending in said portion of the main line (3, 3 ′) to the side of the portion of conductor (4, 4 ′) is connected, respectively, and with a capacitive coupling with the latter is distributed along the segments located side by side or face of said conductors (4, 4 ′ and 6, 6'). These portions of the conductors (6, 6 ′) is not connected to form, together with the coil (2) and the conductor portions connected (4, 4 ′) and not connected (6, 6 ′), and possibly with portions of the power supply line (7, 7 ′) are connected to said additional conductor portions (6, 6 ′) are not connected, at least one additional oscillating circuit (9) having a different resonance frequency.
