1. A power conversion apparatus comprising:

  • first and second DC busses;

    a neutral node;

    an inductor configured to be coupled to a load; and

    an inverter circuit coupled to the first and second DC busses, to the neutral node and to the inductor and configured to selectively couple the first and second DC busses and the neutral node to a first terminal of the inductor to generate an AC voltage at a second terminal of the inductor such that, in a given half-cycle of the AC voltage, the inverter circuit uses a switching sequence wherein the first DC bus, the second DC bus and the neutral node are successively coupled to the first terminal of the inductor.
