| Abstract(in English) | In the conventional Hill-climing method, it takes more time to track the maximum power point for changing solar insolations and the operating point oscillates even after the maximum power point is reached. To achive high-speed tarcking of the maximum power point, this paper proposes a new maximum power point tracking (MPPT) algorithm for photovoltaic array using the output current versus optimal duty factor tables corresponding to insolations change. The proposed method estimates optimal duty factors for several insolations. In addition the proposed method also works well even if solar insolation and the system charactaristics change. Performance of the proposed method is compared with that of the Hill-climbing method through experimental results. |
