“…Hence, this topology is also not considered for further quantitative analysis. Further, the topologies that are given in [12], [15], [21], [23], [27], [31], [32], [35], [36], [38], [39], [40], [41], [42], [43], [45], [48], [56], [71], [73], and [81] are producing less voltage gain when compared to other topologies. So, those are also not considered for quantitative analysis.…”

Renewable energy is identified as a potential alternative to conventional utility grid-based electricity to meet the present-day requirements of a variety of consumers. However, the inadequacy of matching the generated voltage to the customer required rating is still a major constraint. So, to meet the required energy requirements in terms of voltage ratings, power electronics-based DC-DC boost converters are generally used. But the voltage gain produced by traditional DC-DC boost converter may not be sufficient for the renewable energy application, where, the source voltage ratings produced are usually low. Hence, an effective DC-DC boost converter circuit with high gain has to be identified for this purpose. In line with this, many studies have proposed different topologies. Even though there were some studies presented in the literature, all those did not consider various key performance metrics viz., ripple current, voltage stress, voltage gain, number of components used, efficiency, output quality, switching frequency, etc., for the analysis. The effectiveness of any topology has to be evaluated in terms of the above-mentioned factors to understand its usefulness. Hence, keeping this gap in view, this paper presents a detailed theoretical and simulation analysis on state-of-the-art topologies in view of all the key performance metrics. A comparative analysis concerning the number of components used, performance metrics, output quality, transient response analysis, gain factor achieved, switch rating requirement, voltage/current stresses has been conducted. Based on this analysis of the advanced topologies, a better DC-DC converter topology is suggested as the conclusion of this paper.

As for the insufficient nature of the fossil fuel resources, the renewable energies as alternative fuels are imperative and highly heeded. To deliver the required electric power to the industrial and domestic consumers from DC renewable energy sources like fuel cell (FC), the power converter operates as an adjustable interface device. This paper suggests a new boost structure to provide the required voltage with wide range gain for FC power source. The proposed structure based on the boost converter and the quazi network, the so‐called SBQN, can effectively enhance the FC functionality against its high operational sensitivity to experience low current ripple and also propagate voltage and current with low stress across its semiconductors. Furthermore, the switching power losses have been decreased to make this structure more durable. A full operational analysis of the proposed SBQN and its advantages over the conventional and famous structures has been compared and explained. Furthermore, a prototype of the single‐phase converter has been constructed and tested in the laboratory.

As for the insufficient nature of the fossil fuel resources, the renewable energies as alternative fuels are much needed and highly heeded. To deliver the required electric power to the industrial and domestic consumers from DC renewable energy sources like Fuel Cell (FC), the power converter operates as an adjustable interface device. This paper suggests a new boost structure to provide the required voltage with wide range gain for FC power source. The proposed structure based on the boost converter and the quazi network, so-called SBQN, can effectively enhance the FC functionality against its high operational sensitivity to experience low current ripple, and also propagate voltage and current with low stress across its semiconductors. Furthermore, the switching power losses have been decreased to make this structure more durable. Full operational analysis of the proposed SBQN and its advantages over the conventional and famous structures has been compared and explained. To more evaluate the high-step up voltage capability of the proposed SBQN and validate the simulations results, a prototype of the single-phase converter has been constructed and tested in the laboratory.
