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.

“…In contrast, size and weight of the converter can be sizably reduced and higher efficiency offers a similar high voltage gain can be attained by employing TL DC-DC converters [35,36]. Conventional boost and the buck-boost converters [34,[37][38][39][40][41][42][43][44][45][46]. For various applications Ćuk, SEPIC and Zeta topologies are preferred over conventional buck-boost converter for their better efficiency and continuous input current [47][48][49][50][51][52], albeit having higher component count [53].…”

In this paper, a comparative analysis has been presented on various topologies of isolated and non-isolated DC-DC converters. Here, the major focus remains on transformer-less (TL) DC-DC converters, based on the conventional basic boost converter. In addition, to attain high voltage gain, a classification of non-isolated converters based on extendable and non-extendable design has been presented. For comparative and theoretical analysis, the parameters chosen are the number of components utilized by each converter topology, high voltage gain offered, voltage stresses on each component involved and the efficiency of the high gain topologies. For the converters under discussion, operation under ideal and non-ideal conditions has also been highlighted. Based on this study, authors present a guide for the reader to identify various high voltage gain topologies for photovoltaic (PV) systems.

“…Designing high-performance power converter with low cost, small size, and high efficiency makes the electromagnetic interference (EMI) design a more challenging task [1]. The Zeta and the Flyback converters [4][5][6][7][8][9][10][11][12][13] require an additional input/output L-C filter to reduce the switching ripple and noise level at both terminals. For these applications, the Cuk converter seems to be a potential candidate within the basic converter topologies [3].…”

A novel single switch two diode wide conversion ratio step down/up converter is presented. The proposed converter is derived from the conventional single-ended primary inductor converter (SEPIC) topology, and it can operate as a capacitor-diode voltage multiplier, which offers simple structure, reduced electromagnetic interference (EMI), and reduced semiconductor voltage stress. The main advantages of the proposed converter are the continuous input/output current, higher voltage conversion ratio, and near-zero input and output current ripples compared with the conventional SEPIC converter. The absence of both a transformer and an extreme duty cycle permits the proposed converter to operate at high switching frequencies. Hence, the overall advantages will be: higher efficiency, reduced size and weight, simpler structure and control. The theoretical analysis results obtained with the proposed structure are compared with the conventional SEPIC topology. The performance of the proposed converter is verified through computer simulations and experimental results.proposed converter to operate at high switching frequencies. Hence, the overall advantages will be: higher efficiency, reduced size and weight, simpler structure and control.Comparison results with the conventional SEPIC converter show that the proposed modified SEPIC is more suitable for applications that require a high input-to-output voltage conversion ratio. The proposed converter has few extra components compared to the conventional SEPIC converter, and it is regulated by the conventional PWM technique at constant frequency. However, the additional components is outweighed by the significant advantages gained, thus expecting the popularity of this technique to other exiting topologies. The performance of the converter is verified by means of simulation and experimental tests which confirm the operating principles of the proposed converter. 374
