| Abstract: | According to the asymmetric characteristics of photovoltaic array and the disturb to determine the step size of perturbation and observatio-n method(P&O), a new optimized P&O was proposed. Applying this method to MPPT of PV cells, simulation and experimental results show that this new method improves the utilization of PV cells with rapid and accurate MPPT track under the change of ambient condition. |
