An improved perturb-and-observe maximum power point tracking algorithm is presented that incorporates a current compensated converter. In order to achieve fast response and accurate holding of the maximum photovoltaic (PV) power under changing environmental conditions, a variable perturbation step size is adopted. In addition, a control parameter alpha, is introduced to enhance the tracking sensitivity during abrupt changes of environmental conditions. Instead of directly perturbing the switch… CONTINUE READING
