| Abstract: | One flaw of the classical perturbation and observation method is that it can cause power loss when it is used to track the maximum power point of PV cell. In order to overcome this flaw, an improved perturbation and observation method with variable step is presented and validated by simulation using MATLAB. The simulation results demonstrate that the improved perturbation and observation method can track the maximum power point of PV cell accurately without causing power loss. So it is strongly feasible. |
