Abstract
Official abstract text for this publication.
A power conversion system for providing power to an electrical grid is described. The system includes a power converter coupled to a direct current (DC) power source. The system also includes a contactor coupled to the power converter and the electrical grid and configured to selectively electrically couple the power converter to the electrical grid. The system also includes a system controller communicatively coupled to the power converter and the contactor and configured to close the contactor to electrically couple the power converter to the electrical grid and to activate the power converter when a DC voltage provided has remained higher than a voltage level for a length of time. The system controller is also configured to deactivate the power converter, while the contactor is maintained in the closed position, when an alternating current (AC) power output has remained lower than a power level for a length of time.
First claim
Opening claim text (preview).
What is claimed is: 1. A power conversion system for providing power to an electrical grid comprising: a power converter coupled to and configured to receive power generated by a direct current (DC) power source; a contactor coupled to said power converter and said electrical grid and configured to selectively electrically couple said power converter to said electrical grid; and a system controller communicatively coupled to said power converter and said contactor, said system…
