Abstract: The present invention relates to a magnetic resonance charging system comprising a voltage source (1) and an inverter (2), said inverter (2) comprising a parallel LC inverter resonant circuit (3) and at least one charging plate (4), characterized in that said inverter resonant circuit (3) comprises a capacitor (32) connected in parallel to a primary winding (33) of said at least one charging plate (4) and in that said inverter (2) further comprises: a measuring means (5) for measuring the instantaneous voltage across said inverter resonant circuit (3), a phase shifter (6) connected to said measuring means (5) an excitation means (7) connected to the phase shifter (6), able to inject energy from said voltage source (1) into the inverter resonant circuit (3) during each cycle observed by the measuring means (5), with a phase shift indicated by the phase shifter (6). The present invention also relates to a method of operating a charging system according to the invention.

Abstract: An assembly (1) for detecting an electric discontinuity that includes an exciter (6) connected, via at least one capacitor, to two contacts (2, 3) normally connected between them by an electrically conducting member (4). The circuit outside the exciter defines a resonating circuit having an impedance that changes upon the opening of one of the contacts. The frequency of the detection circuit, which varies between two values corresponding to the two open or closed states of the contacts, is used by an electronic processing module (8) that generates a dysfunctional signal upon opening of one of the contacts. The invention can be used in numerous fields, such as transport, handling, storage, etc.
