1. A power conversion system for converting a dc voltage to a pulsed ac voltage, comprising:

  • a dc voltage source including a plurality of source terminals providing three or more electric potentials;

    a switching circuit arranged to connect one of the source terminals of the dc voltage source selectively to an output terminal of the switching circuit; and

    a controller configured to produce a pulsed ac output voltage at the output terminal from the potentials of the dc voltage source by controlling an on time for connecting each of the potentials of the dc voltage source to the output terminal.
