“…This converter realizes minor ripples while maintains high voltage gain with only single inductor and single switch. Higher gain was archived in topologies in [107][108][109][110][111][112], but they implement two inductors and two switches. The HBC topology has the advantages such as low cost design and potential to employee in high power applications.…”

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.

Summary This paper proposed a new single‐ended primary inductor converter (SEPIC)‐boost DC‐DC converter that uses only one auxiliary switch to create soft switching condition for all semiconductor devices. The auxiliary circuit comprises one power switch (Sa), one resonant inductor (Lr), one resonant capacitor (Cr), and one diode (Do2). The auxiliary switch (Sa) controls the resonance during switching instants. The converter has simple structure and its control circuit remains pulse width modulation (PWM). Besides, the proposed converter has high voltage gain without using any transformer or coupled inductors. In addition, the auxiliary switch is not located in the main power path. Moreover, using soft switching techniques is the best way for reducing the size, weight, and volume of the converter. Furthermore, reduction of input inrush current and voltage stress for the main switch is obtained by using SEPIC‐boost structure. A laboratory prototype converter is designed and implemented. The experimental results presented confirm the theoretical and features of the proposed converter.

“…The conventional boost converter is used for high step up applications with high current ripples for power system which causes conduction losses. Most of the high step up converter is affected with high input current because of the inductance values (Al-Saffar & Ismail, 2015;Hsieh, Chen, Liang, & Yang, 2013;Kim & Moon, 2015;. To reduce that, the switching frequency has to be increased and hence it reduces the voltage stress occurring in the switches (Fardoun & Ismail, 2010;Wai, Lin, Duan, & Chang, 2007).…”

A non-isolated high voltage gain DC-DC converter has been presented in this paper. The boost, SEPIC and modified SEPIC converters were analyzed and their performance was compared with the proposed converter. The proposed converter has been designed for the input voltage of 15 V and an output voltage of 150 V with 100 W output power. The efficiency of the converter obtained was 92.5%, which is higher than that of the other converter models which were analyzed. Also, the proposed converter utilizes reduced input current and shows low switching voltage stress. The time response analysis conveys that the proposed converter settles to the steady state voltage and current faster than the other compared converters.
