Abstract
Power supplies and methods of use thereof are provided, where a power supply includes an input configured to receive input AC power an output configured to provide output AC power to a load, at least one power converter coupled to the input and configured to convert the input AC power into the output AC power, a controller coupled the at least one power converter. The controller is configured to adjust at least one parameter of the output AC power provided by the at least one power converter, detect, in response to adjusting the at least one parameter of the output AC power, at least one of an adjusted input AC power or an adjusted output AC power, and determine that a fault has occurred based on the at least one of the adjusted input AC power or the adjusted output AC power.
