MPPT control based on self-adaptive duty-ratio perturbation algorithm

Using perturb- and- observe algorithm to track the maximum power of photovoltaic battery array will generate oscillation around the practical working point. In order to solve the problem,through analyzing the characteristic of the photovoltaic battery and comparing a few MPPT strategies based on the perturb- and- observe method,a self- adaptive duty- ratio perturb- and- observe algorithm is adopte…
