Abstract
Official abstract text for this publication.
A system for providing power from solar cells whereby each cell or cell array is allowed to produce its maximum available power and converted by an operatively connected DC/DC converter. Each cell or cell array has its own DC/DC converter. In one form the system includes one or more solar generators wherein each solar generator has one to nine solar cells; a maximum power tracker operatively associated with each solar generator, each maximum power tracker including a buck type DC/DC converter without an output inductor, each maximum power tracker being operatively connected in series with each other; an inductor operatively connected to the series connected maximum power trackers; and means for providing electrical power from the inductor to load means, wherein each maximum power tracker is controlled so that the operatively associated solar generator operates at its maximum power point to extract maximum available power.
First claim
Opening claim text (preview).
What is claimed is: 1. A system, comprising: a plurality of solar units, each solar unit of the solar units comprising: a solar generator having at least one solar cell to generate electric power; only one pair of output connections to provide output; and a DC/DC converter coupled between the solar generator and the pair of output connections to receive electricity provided by the solar generator in entirety and to provide the output via the pair of output connections, wherei…
