Claims (4)
1. Direkt spänningsomvandlare, omfattande en transistor-ström-ställare (Tl), med vars kollektor-emittersträcka parallellkopplats en kondensator (C2; C3), och med en transformator (Tri) i huvud-strömkretsen, vilken transformator i sekundärlindningen uppvisar en likriktardiod (Dl) i längsgrenen och en nolldiod (D2) i tvär-grenen, kännetecknad av att i en annan parallellgren tili transistorströmställarens (Tl) kollektor-emittersträcka anord-nats en andra kodensator (C3; C2), att av kondensatorerna (C2, C3) den ena är dimensionerad säsom skyddskondensator (C3) för avskil-jande av transistorströmställaren (Tl) och den andra säsom en av-magnetiseringskondensator (C2) för transformatorn (Tri), och att skyddskondensatorn (C3) är medelst en synkront med styrspänningen för transistorströmställarens (Tl) styrspänning styrd omkopplare (T2) under övergängen hos transistorströmställaren (Tl) frän ledande tili spärrat tillständ ansluten tili dennas kollektor-emittersträcka.
2. Omvandlare enligt patentkravet 1, kännetecknad av att för tili- och fränkoppling av skyddskondensatorn (C3) anord-nats en via en pä primärsidan tili transistorströmställarens (Tl) kollektor-emitterkrets ansluten strömtransformator (Tr3) styrd kopplingstransistor (T2), vars bas-emittersträcka är ansluten
