Abstract：As one of main forms of solar energy utilization, photovoltaic array is vulnerable to the shadow effect, thus its P-V output characteristic curve contains more than one peak. As a result, it is difficult for the conventional algorithms of maximum power point tracking (MPPT) to track the global maximum power point. Based on the approximate proportional relationship between the photovoltaic (PV) array maximum power point current and short circuit current, a novel algorithm is proposed in this paper. The proposed algorithm can guarantee the tracking speed as well as accuracy without any additional circuits. Tracking performance of the proposed MPPT method and global search method was compared based on a 1kW rated boost converter. The experimental results indicate that the proposed MPPT algorithm is effective.
