Maximum Power Point Tracking in PV Arrays with High Gain DC-DC Boost Converter

Photovoltaic (PV) system is an electrical generator that has been widely used. Ease of implementation, supported by a large number of potentials and needs of Green Energy, has become a factor in the increasing number and quickly applied to PV arrays. However, PV arrays have constrained related to generator conversion efficiency and the amount of power produced due to inconstant irradiation and temperature. This problem can be solved by a Maximum Power Point Tracking (MPPT) approach. This article discusses the MPPT technique with High Gain DC-DC Boost Converter using the Perturb and Observe (P&O) algorithm. The same P&O algorithm is also tested in the conventional converter to show performance and superiority of each converter. The results obtained show the advantages and disadvantages of each converter used in MPPT by P&O algorithm.
