A simulation model of photovoltaic cell was introduced;the principle of the realization of MPPT by using the duty-cycle perturbation method was analyzed. In order to further simplify the algorithm,the feasibility of realization of MPPT based on output current detection was analyzed;the principle of the algorithm and the realization thought were explained;the Matlab simulation model was established and simulation experiment was done. The correctness of the algorithm was proved by the simulation result.
