Abstract
The magnitude and wave shape of instantaneous power draw from a single phase alternating current power source to a power converter is controlled by a closed loop power control scheme independent of the direct current output voltage of the converter. A fast averaging methodology for the value of control magnitude and wave shape of the instantaneous power draw by the converter from the alternating current source can be used in the closed loop power control scheme to limit the magnitude of power draw.
