Title (EN) ELECTROMAGNETIC INTERFERENCE SUPPRESSING DEVICE
(FR) DISPOSITIF PERMETTANT D'ELIMINER UNE INTERFERENCE ELECTROMAGNETIQUE
Abstract:
(EN) An electromagnetic and/or electric interference suppression device that reduces the severity of electromagnetic and/or electric interference of an asymmetric system. The suppression device utilizes an antenna to develop a voltage that is ideally equal to the interference voltage developed from interference signals. A tuned circuit having two opposing diodes, a capacitor, and an inductor mounted in series with each other, to create a voltage that approximates as closely as possible, the interference voltage, neutralizing its effect on an asymmetric system.
(FR) L'invention a trait à un dispositif permettant d'éliminer une interférence électromagnétique et/ou électrique, ce qui a pour conséquence de limiter la gravité de l'interférence électromagnétique et/ou électrique d'un système asymétrique. Ce dispositif utilise une antenne pour donner lieu à une tension qui est idéalement égale à la tension d'interférence issue de signaux d'interférence. Un circuit accordé comportant deux diodes en opposition, un condensateur et une bobine d'inductance, le tout monté en série, permet de créer une tension s'approchant le plus près possible de la tension d'interférence, neutralisant, de ce fait, les effets de celle-ci dans le système asymétrique.
