摘要：An electrical converter () having an active diode-clamped multilevel topology isshown. Each clamping diode is connected in antiparallel with a switch (SA, SB). Theconverter comprises polyphase supply phases (A, B, C) each of which are connected via arespective phase leg () to dc rails () and a dc-link capacitor. The dc-link capacitor includes
a plurality of series-connected capacitors (). A controller is configured to, in response toan event signal, for each phase leg, activate a combination of switches therein to form apair of parallel conduction paths to a midpoint () between two capacitors in the dc-linkcapacitor, thereby connecting each phase to the same node.
