Abstract

Det er beskrevet høyfrekvens elektrisk oppvaraiingsanordning hvori metalldeler (10) blir oppvarmet mens de blir fremført, enten for gløding eller smisveisningsformål, og hvori den elektriske oppvarmingsstiømmen blir matet fra en halvleder likestiøms til vekselstiømsveksetetter (2-5, 8) gjennom en lasttilpasnings- og frekvensstyrekrets (13) som opprettholder den ønskede laststiømmen og stiømfrekvens med endringer i lastimpedansen forårsaket av metalldelene (10) mens de blir fremført.
