“…In terms of the number of power switches (bidirectional), it stands out by requiring only two switches, while other converters typically have more 36 . The Multi-Input SEPIC converter boasts fewer diodes compared to traditional converters, which often require 5 or 3 diodes 33 . Furthermore, the Multi-Input SEPIC converter achieves an efficiency of over 96%, surpassing the lower efficiency percentages of 95%, 94%, and 88%-94% seen in other converters 35 .…”

“…Further the SEPIC topology technique can be implemented by Buck and Buck-Boost converter as well, where the multiple DC voltages can be connected to the DC micro grid bus. But the main intention is not regarding the input DC but the output desired voltage, which can be supplied further to plenty of DC power applications 33 .…”

“…When the switch is turned off entirely, the output voltage drops to zero, although a temporary surge of energy may be released during this process 29 – 32 . This complete shutdown capability makes SEPICs well-suited for situations where battery voltage fluctuates significantly 33 – 38 . For example, a lithium-ion battery's voltage typically drops from 4.2 to 3 V as it discharges.…”

The development of DC microgrids is reliant on multi-input converters, which offer several advantages, including enhanced DC power generation and consumption efficiency, simplified quality, and stability. This paper describes the development of a multiple input supply based modified SEPIC DC–DC Converter for efficient management of DC microgrid that is powered by two DC sources. Here Multi-Input SEPIC converter offers both versatility in handling output voltage ranges and efficiency in power flow, even under challenging operating conditions like lower duty cycle values. These features contribute to the converter's effectiveness in managing power within a DC microgrid. In this configuration, the DC sources can supply energy to the load together or separately, depending on how the power switches operate. The detailed working states with equivalent circuit diagrams and theoretical waveforms, under steady-state conditions, are shown along with the current direction equations. This paper also demonstrates the typical analysis of large-signal, small-signal, steady-state modeling techniques and detailed design equations. The proposed configuration is validated through the conceptual examination using theoretical and comprehensive MATLAB simulation results. Detailed performance analysis has been done for different cases with various duty ratios. Finally, to show the competitiveness, the multi-input SEPIC topology is compared with similar recent converters.

“…Buck converters, also known as step-down converters, are widely used in applications where a regulated voltage needs to be obtained from a higher voltage source. Examples of such applications are industrial applications [1,2], like motor drives or factory automation [3,4], telecommunications [5], solar power systems [6], automotive [7], and voltage regulators [8][9][10][11][12]. This ability to reduce the voltage level is essential in many electronic devices, and in the literature, different topologies, starting with the classical step-down buck converter [13], other types of non-isolated [14,15] converters or isolated step-down converters [16][17][18] can be found.…”

This paper aims to outline the process of dimensioning a controller tailored for a fourth-order step-down converter. In order to conduct a thorough small-signal analysis, it is imperative to find the state–space model in matrices form. Given its fourth-order nature, the control-to-output transfer function also aligns with this order, although its degree is ultimately reduced to a second-order using the tfest function. It is remarkable that the design of the type III error amplifier assumes a central position in the overall controller design process. The theoretical analysis was then subjected to rigorous validation via simulation, with particular attention paid to the step response in both input voltage and output resistance. This study developed from the desire to validate the efficacy of reducing the control-to-output transfer function degree using the tfest function, aiming to highlight a fourth-order converter to which controller design theory can be applied, related to that for a second-order converter.
