1. A power converter, comprising:

  • a power input configured to receive input power from an AC power source;

    a power output configured to provide output power to a load;

    a battery interface configured to exchange DC power with a battery; and

    power converter circuitry coupled to the power input, the power output, and the battery interface, the power converter circuitry adapted to, in a first interconnection configuration, convert the input power into the DC power at the battery interface, and further adapted to, in a second interconnection configuration, convert the DC power at the battery interface into the output power, the power converter circuitry having;

    a power line coupled to at least one of the power input and the power output;

    a transformer;

    a first connection node switchably connected to the power line in the first interconnection configuration and switchably connected to the transformer in the second interconnection configuration; and

    a second connection node switchably connected to the transformer in the first interconnection configuration and switchably connected to the power line in the second interconnection configuration.
