| Abstract: | In this paper,a model of solar cell using MATLAB is established based on its volt-ampere characteristics. The principle and characteristic of some DC-DC conversion are also introduced,which applied to maximum power point tracking. And establish a model of DC-DC conversion with PSB in the MATLAB,a relative perfect simulated result is obtained. Then,hardware of system is designed based on ATmega16 and the principles of main circuit、measurement circuit、drive circuit and control circuit are made. Finally,the proposed control methods are proved practical by the results of experiments. |
