Abstract
An inductive filtering device includes a magnetic core at least one electrical cable wound around the magnetic core so as to form at least one turn, the electrical cable being intended to convey an electrical signal possessing at least one undesirable AC component superposed on a fundamental frequency of the electrical signal, and an electrically conductive screen that is electrically insulated from its environment, the screen being placed between the magnetic core and the electrical cable so as to allow, in the screen, via electromagnetic induction, a current to be generated the frequency of which is higher than the fundamental frequency, the screen being configured so as not to allow a current to flow in a direction parallel to that of the one or more turns formed by the winding of the electrical cable around the magnetic core.
