| Shadows play a key role on mismatch of the solar battery group and total power generation efficiency. In order to slove the issue of the solar battery group mismatch.the corresponding impact factors were studied and analyzed. Then a kind of dynamic interconnected technology combined with SOPC (System On Programmable Chip) technology was put forward. It can effectively solve hot spot effect induced by the solar battery group mismatch; meanwhile it raised the power generation efficiency of the whole solar system.First of all, the main influence factors on the solar battery group mismatch were studied and analyzed. Secondly, the main influence factors were analyzed. The solar battery group dynamic interconnecting technique based on FPGA was proposed, which separated the shadowing part from the original solar battery group effectively. Then a special DC/DC Converter for the rterial part and the lesser part was carried out. Finally, the two DC/DC Converters were matching-interconnected.Finally, the whole system was timing simulated and whole output efficiency was tested. The obtained data was analyzed. It was concluded that the designed solar battery dynamic interconnected system can effectively solve the problem of solar battery group mismatch. The conversion efficiency for solar battery group was maximally promoted for28%in the case of shadow mismatch. |
