Abstract

Fremgangsmåte for undertrykkelse av radiofrekvensut- stråling fra en elektrisk drlvlnnretnlng og anordning ved en elektrisk drlvlnnretnlng for undertrykkelse av radiofrekvensutstråling fra den elektriske Innret- ningen. Den elektriske drlvlnnretnlngen er av den art som Innbefatter en elektrisk motor (11) forsynt med en elektrisk strømforsyningskilde via en elektronisk styrer (12) med en høyhastighets swltch-lnnretnlng som genererer høyfrekvent energi. En elektrisk skjerm (9) er anordnet for å motta radlofrekvensenergl og er til- bakekoblet med Inngangssiden til høyhastlghets switch- Innretnlngen.
