Abstract
The magnitude and wave shape of instantaneous alternating current and power delivered from a converter's single phase alternating current output is controlled by a closed loop power control scheme independent of the direct current input voltage to the converter. A fast averaging methodology for the value of control magnitude and wave shape of the instantaneous power delivered from the alternating current output can be used in the closed loop power control scheme to limit the magnitude of delivered power. The closed loop power control scheme can be used in both power grid-tied applications and stand-alone non-powered load line applications.
