“…The shortcomings of conventional buck-boost converter such as output voltage of reciprocal polarity and palpitated characteristics of load current can be overcome by SEPIC converter [141]. Rasoul Shalchi et al in [142] proposed a high step up DC-DC converter by combining an extensive switched capacitor and a conventional SEPIC converter for PV application. The main prospects of this introduced topology are lower number of elements and superior potential gain, presence of low ripples, simpler control strategies, and consistent input current.…”

Sustainable energy exhibited immense growth in the last few years. As compared to other sustainable sources, solar power is proved to be the most feasible source due to some unanticipated characteristics, such as being clean, noiseless, ecofriendly, etc. The output from the solar power is entirely unpredictable since solar power generation is dependent on the intensity of solar irradiation and solar panel temperature. Further, these parameters are weather dependent and thus intermittent in nature. To conquer intermittency, power converters play an important role in solar power generation. Generally, photovoltaic systems will eventually suffer from a decrease in energy conversion efficiency along with improper stability and intermittent properties. As a result, the maximum power point tracking (MPPT) algorithm must be incorporated to cultivate maximum power from solar power. To make solar power generation reliable, a proper control technique must be added to the DC–DC power converter topologies. Furthermore, this study reviewed the progress of the maximum power point tracking algorithm and included an in-depth discussion on modern and both unidirectional and bidirectional DC–DC power converter topologies for harvesting electric power. Lastly, for the reliability and continuity of the power demand and to allow for distributed generation, this article also established the possibility of integrating solar PV systems into nanogrids and picogrids in a sustainable environment. The outcome of this comprehensive survey would be of strong interest to the researchers, technologists, and the industry in the relevant field to carry out future research.

“…Several topologies are derived with extendable form either in increasing the turns ratio of the coupled inductor in the converter [35] and adding N number of voltage multiplier cells [36]. In [36], the voltage gain of the converter is (N + 1)D/(1 − D) with the component count of 11, whereas the proposed topology presents the voltage gain of (1 + 2ND)/(1 − D).…”

“…[32][33][34]. More switches and passive components increase the bulkiness of the converter and the complexity [35][36][37][38][39][40][41][42][43][44][45][46][47][48]. All these issues are considered for which a new dc-dc converter without a transformer is proposed by integrating the switched inductor and voltage-lift cell into a common branch to obtain a Hybrid Switched Inductor based Voltage-Lift (HSIVL) converter.…”

This paper proposes a novel non-isolated high voltage gain dc–dc converter with a boost2 (B2) technique. The derived single-switch hybrid voltage-lift topology generates a higher voltage conversion ratio with less component counts than traditional voltage-lift converters. Furthermore, to show its superiority, the proposed topology is compared with other recent non-isolated dc–dc converters in terms of the number of power components such as inductors, capacitors, diodes, and switches. Moreover, the voltage stress across the power switch is less than the output voltage, which results in using low-rated components and reducing the converter cost. The steady-state analysis of the proposed topology is carried out with the operating modes in continuous and discontinuous conduction modes. The critical inductance for the proposed converter is derived for design considerations. Compared to the other traditional step-up converters, the stresses across the power diodes are highly reduced. The analysis related to the addition of an expander cell with the topology is performed concerning boundary conditions. An efficiency model with loss calculation is presented. Furthermore, the reliability analysis is performed with the military handbook to determine the failure rate of the converter’s components. Finally, the simulation and 50 W prototype model for experimental validation prove the strength of the proposed topology.

In power electronics, it is necessary to select the best converter circuit topology that has good performance among different converters. The single-ended primary inductor converter (SEPIC) has good performance and is advantageous among different direct current/direct current (DC/DC) converters. In this paper, a design of a SEPIC converter is made by selecting the values of its components according to the required output voltage and power. The design is made by an assumption that both of its inductors have the same value. The converter is tested by using MATLAB Simulink successfully. Later, its output voltage is regulated by using a proportional integral (PI-controller) through tuning its proportional and integral gains. Finally, the SEPIC converter is connected to a single-phase full-bridge inverter to supply its required DC voltage. The role of the SEPIC converter is to regulate the dc-link voltage between its output side and the inverter. The results showed the success of this connection to supply alternating current (AC) loads with low total harmonic distortion (THD).
