“…However, some of the single-objective metrics may include helpful information if they are provided within a fair evaluation condition. As comprehensively studied in this paper and according to the most recent publications in 2022 and 2023 [260]- [277], most of these NHSDCs are the permutation or recombination of the current voltage boosting techniques, which reveals itself in the frequent comment of the reviewers about the lack of novelty in the peer review process. In addition, the current topologies have acceptably high voltage gain, and increasing the voltage gain to much higher values is not practical in most of the cases.…”

Due to the extensive role of non-isolated high step-up DC-DC converters (NHSDC)s in industrial applications and academic research, many of these pulse width modulation converters have been presented in recent years. For each of these NHSDCs, some claims are introduced to verify its capabilities and features, which has been investigated in some review papers with different frameworks. Dissimilar to previous review papers, which have focused on the classification and derivation of voltage boosting techniques, this paper aims to evaluate the converters from various topological and operational points of view, and determine the superiority of each technique and converter according to applications. Some of these metrics are voltage gain, stresses, ripple, cost, power density, weight, size, control complexity and components count which lead to a comprehensive comparative study. Then, as the main purpose of this paper, effectiveness of these metrics is assessed to show how well they can lead us to the fair comparison results. Moreover, some new figures of merit are proposed in this paper to provide a helpful guideline in power electronic converters comparison studies. Finally, the feasibility discussion of single-and multi-objective figures of merit is followed by general practical conclusion and outlook about the NHSDC structures.

“…An ultrahigh step-up DC-DC converter consisting of two boosting stages, a linked inductor and switching capacitors, was proposed by the authors in [7]. High-voltage gain, minimal voltage stress on switches, input current continuity, and the presence of common ground between the source and load are some of the converter's advanced features.…”

Analyzing the Effectiveness of Single Active Bridge DC-DC Converter under Transient and Load Variation

Over the last couple of years, the use of DC-DC converters is being widely used in several applications. The need for a reliable and robust converter for application is very important because of the social impact that it can have on the losses in high-power electronics applications and output efficiency. This paper gives a comprehensive review of single-active-bridge (SAB) converters. The detail modelling and performance evaluation of SAB topology with PI controllers are also presented in this article. The performance of SAB topology is analyzed under transient and load variations. Due to the nonlinear behavior of SAB topology, the traditional PI controllers have not minimized transient disturbances. The major problem with the usage of conventional controllers and traditional configurations for the SAB converter are the ripples, which are generated in output voltage and current. These ripples severely affect the performance of the SAB converter. An effort has been made to analyze and contribute to the importance of a robust controller to mitigate the converter dynamics. This article also gives an in-depth dynamic analysis of SAB converters, which were controlled using PI controllers and failed to perform satisfactorily under non-linearities.

This paper proposes a reconfigurable fault‐tolerant multiport converter for a renewable energy–based standalone system. The operation of the proposed converter for various single and multiple switch faults is discussed and verified with the help of a laboratory prototype. Experimental findings showcase the converter's ability to seamlessly connect renewable sources with a DC bus and an energy storage device, ensuring a consistent, regulated power supply despite single or multiple switch faults. Furthermore, a thorough examination of performance metrics including stress, loss, cost, sensitivity, and reliability affirms the effectiveness and resilience of the proposed approach. Comparative analysis solidifies the notion of the converter's superiority, emphasizing its fault tolerance, efficiency, and reliability when contrasted with alternative solutions.
