| Abstract: | In order to search out a method for the perfection of solar cell＇s maximal power point tracking, this thesis starts with the analysis on mathematical model of solar cell and its output characteristic under some external variables, including temperature, light and intensity. Then it elaborates the principle of the technology -Maximal Power Point Tracking, and proposes a new algorithm called adaptive variable-step size, to overcome the shortcoming of the traditional algorithm. The simulation works reveal that this new algorithm is able to quickly track the maximum power at the maximum power point. |
| Keywords: | solar cell MPPT variable-step incremental conductance method |
