A Comprehensive Review of DC–DC Converter Topologies and Modulation Strategies with Recent Advances in Solar Photovoltaic Systems

Abstract

Renewable Energy Sources (RES) showed enormous growth in the last few years. In comparison with the other RES, solar power has become the most feasible source because of its unique properties such as clean, noiseless, eco-friendly nature, etc. During the extraction of electric power, the DC–DC converters were given the prominent interest because of their extensive use in various applications. Photovoltaic (PV) systems generally suffer from less energy conversion efficiency along with improper stability and intermittent properties. Hence, there is a necessity of the Maximum power point tracking (MPPT) algorithm to ensure the maximum power available that can be harnessed from the solar PV. In this paper, the most important features of the DC/DC converters along with the MPPT techniques are reviewed and analyzed. A detailed comprehensive analysis is made on different converter topologies of both non-isolated and isolated DC/DC converters. Then, the modulation strategies, comparative performance evaluation are addressed systematically. At the end, recent advances and future trends are described briefly and considered for the next-generation converter’s design and applications. This review work will provide a useful structure and reference point on the DC/DC converters for researchers and designers working in the field of solar PV applications.

Single-Switch Bipolar Output DC-DC Converter for Photovoltaic Application

“…Therefore, a standard value of 470 µF is chosen. With respect to the voltage ripple, the application of Equation (19) with C 1 = C 2 = 470 µF allows to obtain a ripple of 0.4%, when the load is maximum, which is when D = 0.52 and R o = 11.1 Ω.…”

“…For the control of the converter, several strategies can be applied to the proposals in the technical literature for converters of one input and one output [18][19][20][21][22][23][24]. In this work, the technique chosen allows maximum power point tracking.…”

“…This topology is effective for this type of application, with high efficiency and with the use of only one controlled power switch. In addition, for the control of the maximum power point, any proposed technique for one input and one output converter can be used [18][19][20][21][22][23][24].…”

Dynamic Analysis of the Switched-Inductor Buck-Boost Converter Based on the Memristor

“…Power electronic technology has developed rapidly in recent years. Like other power electronic devices, the DC-DC converter has also penetrated into many fields, including energy science [1], physics [2], industry [3], automation [4][5][6], and so on.…”

Performance comparison of different control strategies for the regulation of DC-DC negative output super-lift luo-converter

“…While in [13] the overviews of virous control scheme have been presented in this paper in order to select the apportuinte method for DC-DC converters. In [14],this article introduces a comprehensive review about DC-DC converters in two types isolated and nonisolated for renewable energy application. It can be seen that the super lou converter and ultera super lift converter have high gain ratio thus these converters are very benficial for the application that need high step up output voltage.…”
