| Abstract(in English) | Partial shading on a photovoltaic (PV) panel is well known to trigger not only significantly reduced power generation but also multiple maximum power points (MPPs). Various kinds of differential power processing (DPP) converters have been proposed and developed to address partial shading issues. Meanwhile, power generation of PV panels substantially decreases as panels deteriorate due to damage, and therefore, PV panels are desirably diagnosed for early detection of degradation malfunctions. In recent years, autonomous electrical diagnosis techniques based on ac impedance measurement are considered as a promising solution. Conventional electrical diagnosis techniques, however, require expensive instruments. This paper proposes a novel DPP converter as well as an electrical diagnosis technique using the DPP converter. The operation analysis and experimental verifications of the proposed DPP converter were performed. The results demonstrated not only the improved power yield from partially shaded PV panels but also the electrical diagnosis capability of the proposed DPP converter. |
