Abstract

Et energiomformingssystem er fremvist, hvilket omfatter en elektrisk maskin (32) eller en gruppe av elektriske maskiner (32), hvor hver separate viklingsgruppe (50) innenfor en elektrisk maskin (32) eller individuelle elektriske maskin (32) i gruppen av elektriske maskiner er galvanisk koblet til en assosiert AC/DC-omformerenhet (likeretter) (33). Energilagringskretser (DC-linker) (34) for omformerne (33) er koblet til hverandre i serie og skaper en felles DC-høyspenning (45). Videre er hver separate viklingsgruppe (50) innenfor en elektrisk maskin (32) eller individuelle elektriske maskin (32) i gruppen av elektriske maskiner (32) omgitt av en elektrisk skjerm (60, 60A-E) av ledende eller halvledende materiale for omfordeling av elektriske potensialer innenfor systemet. Potensialomfordelingen tillater at spalteisolasjon for elektriske maskiner (32) kan utformes for betydelig lavere spenning enn den felles DC-høyspenningen (45). Dette betyr tynnere spalteisolasjon, bedre feildeteksjon og maskinstørrelsen blir betydelig mindre enn for tilsvarende maskiner med høyspenningsisolasjon.
