Definitions

  • An electrical inverter arrangement comprises a polyphase transformer having a delta-connected primary winding and a delta-connected secondary winding. Positive and negative DC supply lines are provided, and the three junction points of the primary windings are connected to both supply lines through respective electronically controllable switch means. Depending on which switch means are closed, each primary winding can either have 0 volts across it, the full supply volts across it, or half of the full supply volts across it.
  • FIG. 1 is a schematic circuit diagram of one electrical inverter arrangement embodying the invention
  • FIG. 7 is a schematic circuit diagram of a further arrangement embodying the invention.
  • the said winding means is one of a set of polyphase-connected primary windings, and including a set of polyphase-connected secondary windings mutually inductively coupled with the primary windings.
