ABSTRACT:
A power converter converts AC input power into AC output power to which a load is connected. This power converter comprises a controller for controlling power converting operation of the power converter, a DC voltage detector for detecting a DC voltage of the DC power to provide a DC voltage signal, a first reference generator for generating a first reference, an output detector for detecting a condition of the AC output power to provide an output condition signal, a second reference generator for generating a second reference in response to the output condition signal, a condition detector for detecting a condition of the AC input power to provide an output condition signal, and a selector for supplying the second reference to the controller when the input condition signal is provided.
