Claim 20:
21. A method of operating a power converter system including an input configured to receive input power from a power source, power conversion circuitry coupled to the input and configured to convert the input power into three-phase output power, and an output configured to provide the three-phase output power to a load, the method comprising:
detecting a first voltage of a first phase of the three-phase output power,
detecting a second voltage of a second phase of the three-phase output power,
detecting a third voltage of a third phase of the three-phase output power,
determining if the first voltage, the second voltage, and the third voltage are within a tolerance; and
in response to determining that the first voltage, the second voltage, and the third voltage are within the tolerance, operating the power conversion circuitry to provide two-phase output power to the output.
