“…The so-called non isolated boost converter, as the name suggests, means that there is no electrical isolation between the input and output, there is a connection on the circuit, and the voltage is increased. Common boost circuits mainly include boost converter, buck boost converter and Cuk Converter [5]. These circuits achieve boost by changing the conduction ratio of switching devices.…”

Hydrogen energy is one of the emerging new energy sources in today’s era. It not only has a wide range of materials and simple production, but also its combustion products have no pollution to the environment and have excellent quality that non-renewable fuels such as coal and oil do not have. However, as one of the most common application forms of hydrogen fuel, hydrogen fuel cell, due to its own design and structural characteristics, not only brings convenience to us, but also has the problems of low output voltage and large fluctuation range. Therefore, only by using DC-DC converter to boost and stabilize the output voltage of hydrogen fuel cell, can we efficiently supply power to the backward circuit and load. Combined with the advantages and disadvantages of single isolated and non-isolated converter, this paper puts forward the converter model combining isolated and non-isolated converter, and then introduces the feedback link to stabilize the voltage. Finally, the circuit model is constructed by using MATLAB / Simulink software to verify the accuracy of theory and analysis.

Solar energy is most admired alternative to traditional energy sources. Special attention is required to improve solar gathering techniques in mountainous regions like Sikkim, where sun availability is unreliable but irradiance level is high. This paper proposes a hardware model for smart autonomous selfadjusting solar panel whose output is fed to DC-DC Cascaded SEPIC-Boost Converter for high voltage renewable based applications. The developed renewable system is designed to adjust the panel in a position where maximum voltage is extracted. The output of the solar panel is fed to the DC-DC cascaded converter. A detailed circuit analysis is performed to evaluate the system's e ciency and voltage gain. The converter is examined with different duty cycles. The proposed converter generates 40 V DC output with 20 V DC input voltage from solar panel at 50% duty ratio and gives 90% e ciency. The feasibility of the converter is con rmed with results obtained from an experimental prototype.

“…Therefore, in a parallel‐connected configuration, a reliable DC‐DC converter with high gain is required to step up the output voltage to desired high levels. Many converter topologies are introduced as boost, Cuk, Zeta, and SEPIC converters capable of providing higher output for a low input voltage in Padhee et al, 6 Koç et al, 7 Kumari et al, 8 and Alsolami and Allehyani 9 and their control in Shen et al, 10 Yin et al, 11 Liu et al, 12 and Wu et al 13 However, realistically, the feasible voltage gains of the above‐mentioned converter topologies are in a limited range, and their power switches have substantial losses. The aforementioned converters are unable to provide high step‐up voltage at the output, as required for many applications.…”

This work proposes a modified high gain DC‐DC converter integrated with two boost converter stages, based on a boost cell and a Z‐source (ZS) cell with a switched capacitor (SC). The proposed converter architecture is simple, with a continuous input current and a wide range of input voltage fluctuation handling capabilities. It also provides a high voltage gain while minimizing voltage stress on semiconductor components. Because of the aforementioned characteristics, the proposed converter is suitable for combining with low‐voltage DC‐sources to high‐voltage DC bus in a variety of applications such as solar photovoltaic (SPV), fuel‐cell, and LED lighting. The operational principles, thermal modeling, steady‐state, and dynamic performance analysis are meticulously carried out on a 400 W laboratory prototype of the proposed converter. The converter's performance is carefully compared with similar existing topologies in terms of total device count and size, the voltage stress on power semiconductors, voltage gain, and peak efficiency. Furthermore, experimental findings show that a 12 V input is boosted to 98.8 V at a duty ratio of 0.3, demonstrating the efficacy of the proposed converter over a comparable structure.
