Abstract
A system for providing power from solar cells where each cell or cell array is allowed to produce its maximum available power and converted by its own DC/DC converter. In one form the system includes: one or more solar generators, each of which has at least one solar cell; a maximum power tracker operatively associated with each solar generator, where the maximum power tracker includes a buck type DC/DC converter without an output inductor, and the maximum power trackers of the solar generators are operatively connected in series with each other; and an inductor operatively connected to the series connected maximum power trackers.
Claims10
A system for providing power from solar cells, comprising:
- a plurality of solar generators, wherein each of said solar generators has at least one solar cell;
- a plurality of series connected maximum power trackers, each of said maximum power trackers operatively associated with a corresponding solar generator of the plurality of solar generators, each of said maximum power trackers including a buck type DC/DC converter without an output inductor;
- and
- an inductor operatively connected to the series connected maximum power trackers to provide electrical power to a load;
- wherein each of said maximum power trackers is controlled to operate the corresponding solar generator at a maximum power point.
