Abstract

Official abstract text for this publication.

A system for providing, from a direct current (DC) voltage source, an alternating current (AC) to an electrical grid outputting a grid voltage, the system including: a transformer for coupling to the DC voltage source through a first switch controlled by a first control signal, and configured to provide a converted voltage based on a DC voltage; a rectifier coupled to the transformer, and configured to generate an envelope voltage of the converted voltage; a plurality of switches coupled to the rectifier to receive the generated envelope voltage of the converted voltage, the plurality of switches being controlled by a plurality of control signals, respectively, and configured to generate the AC from the generated envelope voltage of the converted voltage; and control apparatus coupled to the first switch and the plurality of switches, and configured to provide, based on the grid voltage, the first control signal and the plurality of control signals.
