Title
(EN) POWER SUPPLY FOR PROCESSING OF GASEOUS MEDIA
(FR) ALIMENTATION DESTINEE AU TRAITEMENT DE MILIEUX GAZEUX
Abstract
(EN)
A reactor (1) particularly for the plasma treatment of internal combustion engine exhaust gases, in which a power supply (10) and a reactor bed (2) of the dielectric barrier discharge type are connected directly and enclosed in an earthed metal chamber (17) which both isolates the high voltage power supply and acts as a Faraday cage preventing the emission of electromagnetic radiation from the power supply or plasma.
(FR)
Réacteur (1) destiné notamment au traitement par plasma des gaz d'échappement d'un moteur à combustion interne, dans lequel une alimentation (10) et un lit (2) à décharge à barrière diélectrique sont enfermés dans une chambre (17) métallique mise à la terre, à laquelle ils sont reliés directement. La chambre isole l'alimentation haute tension et se comporte comme une cage de Faraday, empêchant l'émission d'un rayonnement électromagnétique par l'alimentation ou le plasma.
