“…Voltage stress is a key factor to consider because of the switch's significance. Rather than using an input inductor, researchers have developed switching inductor models to increase the conversion ratio by increasing the duty cycle (Chung et al, 2000;Musale and Deshmukh, 2016;Alateeq et al, 2017;Axelrod et al, 2008;Almalaq et al, 2018).…”

This research presents a novel investigation into advancing the operational efficiency and performance of non-isolated buck-boost converters utilized in photovoltaic (PV) systems as charging controllers. The focus of this study lies in the development and integration of a specialized switching inductor configuration, aiming to augment the converter's voltage gain while concurrently mitigating stress imposed on the converter switch. The converter's efficacy is of paramount importance, particularly during stepping-up operations where the duty cycle reduction, a consequence of the integrated switched inductor, contributes to reduced stress. The proposed converter architecture is characterized by its simplicity, necessitating only minimal components for implementation. These include a single capacitor, a pair of diodes, a duo of inductors, and a trifecta of switches. Operating nominally at 12 volts, the converter dynamically adjusts the voltage level in response to varying duty cycles: elevating it beyond the 35% threshold and inversely attenuating it below this parameter. A salient outcome of this endeavor is the curtailment of the dependency on an additional diode (D), resulting in streamlined circuitry. The conceptualized switching inductor model was rigorously assessed using the MATLAB/SIMULINK simulation environment, affording a comprehensive evaluation of its efficacy and robustness. This study thus underscores the viability and potential for significant enhancements in non-isolated buck-boost converter systems through inventive switching inductor integration.

“…PV cells are used to extract a usable electrical form of energy from solar energy. Renewable energy sources, such as solar, give low voltage output that needs to be boosted to higher functional levels [3,4]. The primary consideration in renewable applications is how to achieve high voltage gain while maintaining more efficiency during voltage boosting.…”

Solar photovoltaic (PV) is the most promising renewable energy source available on Earth. Three topologies based on a switched-inductor capacitor and non-isolated high-step-up Cuk converter have been proposed for solar PV. These topologies of the Cuk converter have higher boosting ability than conventional Cuk and boost converters and can reduce the voltage stress of the main switch. A small voltage rating and on-state resistance can give higher efficiency of the converter. The voltage boosting ability of all three topologies was compared to each other and with a conventional Cuk converter. The boosting capability of the third converter was 11 times at 0.75 duty cycle with a solar PV source. These converters do not use a coupled inductor and transformer, which leads to less volume, reducing coupling/core saturation loss, and thus the cost of the converter. A solar PV system of 12 volts was used for boosting with these converters for analysis of the feasibility of use with renewables. The three topologies of the switched-inductor and switched-capacitor (SLSC) Cuk converter were designed and simulated in MATLAB/Simulink to evaluate their effectiveness.

“…The new DC-to-DC converter is known as a Multilevel Boost Converter (MBC). Adding more output multipliers and keeping the main converter part (primary side) is the main aspect of the MBC converter [5][6][7][8][9][10][11][12][13]. The MBC increases the regulated output voltage by adding voltage cells, which are basically switched capacitors cells, but have drawbacks, such as the failure to produce the actual output voltage at higher duty cycles [14].…”

This paper proposes a split-phase control diagram for a new design of a DC-to-DC boost converter which is called PSC-boost and studies its performance. The PSC-boost has two sides, the primary is a PSC converter and the secondary is a DC-to-DC boost converter. The effect of applying the split-phase control diagram helps reduce the output impedance successfully and increases efficiency by 3%. The simulated and analytical results have been proven to validate the effect of the split-phase diagram. The simulated design contains five switches, five capacitors, seven diodes, and three inductors to step up 10V into 160V at 200KHz and 100KHz switching frequencies. The LTspice simulator was used to design and test the proposed model.
