Abstract
Det er beskrevet en vekselretter 15 som omfat- ter et antall parallelt arbeidende vekselret- terbroer (B1,..,B8) hvis utgangsspenninger oppsummeres via summasjonsorganer (19), idet vekselretterbroer (B1,..,B8) påstyres puls- breddemodulert i forhold til en hjelpesty- ringsspenning, og hjelpestyringsspenningene av de enkelte vekselretterbroer (B1,..,B8) har en innbyrdes konstant fasedifferanse, og idet summasjonsorganene (19) oppviser et mellomut- tak (23) som er jordet via en jordforbindelse (24), med hvilken det oppnås en virksom under- trykning av fellesmodus-strømforvrengningene ved at det i jordforbindelsen (24) er anordnet koblingsorganer (49).
