Patent ID: 8217534

Claim:
A distributed power generator system, comprising: a plurality of strings, wherein each string in the plurality of strings includes a plurality of power generator modules coupled together in series; a plurality of combiner boxes coupled to the plurality of strings, wherein each combiner box couples together a set of the strings in parallel; a plurality of DC-DC converters coupled to the plurality of combiner boxes, wherein each DC-DC converter is associated with a combiner box in the plurality of combiner boxes and increases a direct current (DC) voltage output of the associated combiner box; a plurality of maximum power point tracker (MPPT) controls coupled to the plurality of DC-DC converters, wherein each of the plurality of MPPT controls is coupled to a single associated DC-DC converter in the plurality of DC-DC converters and is configured to adjust an output of an associated combiner box in the plurality of combiner boxes based on a condition of the plurality of power generator modules coupled to the associated combiner box; and a second stage combiner box for coupling outputs of the plurality of combiner boxes into a single DC output, the second stage combiner box including an integrated DC-DC converter.
