- Abstract
- Differential power processing (DPP) is a power facility architecture that configures dc - dc converters in parallel with the PV string to improve its power yield. The parallel nature of the DPP architecture brings a number of benefits, such as low converter power rating and low power losses. In this paper, feedfoward DPP structure is applied to improve the efficiency of photovoltaic(PV) power facility. DPP structure is considered to a solution to problems were caused by solar irradiance mismatch. The effectiveness of DPP struture is confirmed by comparing module integrated converter (MIC) structure. Experiments and simulation with feedfoward structure using a DSP(TMS320F28335) hardware design were conducted and the improvement in performance with DPP converters was experimentally confirmed.
