Abstract
The inventive technology, in certain embodiments, may be generally described as a solar power generation system with a converter, which may potentially include two or more sub-converters, established intermediately of one or more strings of solar panels. Particular embodiments may involve sweet spot operation in order to achieve improvements in efficiency, and bucking of open circuit voltages by the converter in order that more panels may be placed on an individual string or substring, reducing the number of strings required for a given design, and achieving overall system and array manufacture savings.
Claims17
A DC-DC power converter comprising:
- an inductor established along a first conductor, between a first and a second node, said first node defined by an intersection of said first conductor, a second conductor, and a third conductor, and said second node defined by an intersection of said first conductor, a fourth conductor, and a fifth conductor;
- a first switch established along said second conductor between said first node and a third node, said third node defined by an intersection of said second conductor, a sixth conductor, and a first power generator connector;
- a first diode established along said third conductor between said first node and a fifth node defined by an intersection of said third conductor, said sixth conductor, and a higher voltage conductor, said first diode allowing flow towards said fifth node;
- a first capacitor established along said sixth conductor between said third node and said fifth node;
- a second switch established along said fourth conductor between said second node and a fourth node, said fourth node defined by an intersection of said fourth conductor, a seventh conductor, and a second power generator connector;
- a second diode established along said fifth conductor between a sixth node and said second node, said sixth node defined by an intersection of said fifth conductor, said seventh conductor, and a lower voltage conductor, said second diode allowing flow towards said second node;
- and
- a second capacitor established along said seventh conductor between said fourth node and said sixth node.
