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

Abstract

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.

A New FL-MPPT High Voltage DC-DC Converter for PV Solar Application

“…The HSU converter was produced by combining a diversified boost and buck-boost converter. The converter made is shown in Figure 6, with the resulting voltage ratio equal to the one given by (10). In addition, the switch in this converter is used to reduce the ripple content of the switching device in a two-phase converter, as shown in Figures 5(b) and 5(c).…”

“…In general, conventional DC-DC converters were used for low-power applications [7]. Meanwhile, for applications requiring high voltage ratios, the development of a power converter topology has also received special attention [8][9][10]. Theoretically, a significant voltage gain in the DC-DC converter is achievable by providing a high duty ratio.…”
