“…Moreover, the proposed converter is designed with only four inductors, each with a smaller value in comparison to the converter in Rajesh and Prabaharan, 16 which employs five inductors with higher values. Additionally, the converters in other studies 3,4,7,8,10,11,13,15,16,22,24,25,[27][28][29][30]32 incorporated a higher count of capacitors than the proposed converter, which can raise internal resistance and adversely affect system performance, ultimately reducing voltage transfer gain. In the proposed converter, the input current remains non-pulsating at both low and high duty cycles, whereas the converters in previous studies 4,15,[31][32][33]35,36 have pulsating input currents at high and low duty cycles.…”

“…In Elsayad et al, 24 the SEPIC converter is enhanced by integrating it with quasi‐Z‐source (qZS) and SI to verify high voltage gain. Additionally, the authors 25,26 modified non‐isolated converter for DC microgrid utility, incorporating a VMC with dual inductors, and in Falahi et al, 27 interleaved non‐isolated converter with soft‐switching capability is proposed. Another non‐isolated boost converter using the voltage‐lift (VL) technique is implemented in Shahir et al, 28 while Mansour and Zaky 4 introduce a boost converter with multiple cells for achieving high gain.…”

SummaryIn this paper, introduces a DC–DC converter design based on a modified hybrid switched inductor‐switched capacitor architecture, aimed at achieving ultra‐high voltage gain in renewable energy systems (RES). The proposed converter involves adding a modified boosting conversion mode (MBM) that interleaves with the main switch to double the voltage transfer gain. Additionally, a modified switched capacitor (MSC) technique, utilizing two diodes as interleaved components, is integrated into the main and auxiliary switches to verify low voltage stress across them. In addition, modified hybrid switched inductors with capacitors (MSIC) and diodes are employed to validate ultra‐high voltage gain. The main advantages of the proposed converter are its high efficiency, low voltage stress across diodes and MOSFETs, and the utilization of low values of inductors and capacitors at high switching frequencies. In addition, the voltage stress across the inductors of the (MSIC) is reduced as the duty cycle increases. Furthermore, the current stress on the main switch is reduced when the charge of capacitor C1 becomes zero. Mathematical models for both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) of the proposed converter are explored. Furthermore, a dual PI controller is designed for the proposed converter to maintain a high fixed output voltage. In addition, the PCB design and experimental testing of the proposed converter to verify the simulation and laboratory results. Specifically, the proposed converter is designed to boost up voltage (30–40 V) to a variable output voltage between 200 and 300 V at 300 W at efficiency 96.7%.
