| Abstract |
When a partial shading occurs in a solar cell, a plurality of maximum points appear in the output characteristic, so that the general maximum power point tracking method can not track the actual maximum point. In order to overcome this problem, several studies have been conducted on the technique of tracking the actual maximum point under partial shading. However, the methods to follow the actual maximum points studied also have disadvantages in that they do not follow the actual maximum power point in all conditions or require additional circuitry. In this paper, we propose an algorithm that can always follow the actual maximum power point without any additional circuit under partial shadow, and verify the proposed algorithm through simulation and experiment. |
