Recently, switched inductor and switched capacitor techniques in DC-DC converter are recommended to achieve high voltage by using the principle of parallel charging and series discharging of reactive elements. It is noteworthy that four diodes, one high voltage rating switch, two inductors are required to design classical Switched Inductor Boost Converter (classical SIBC). Moreover, in classical SIBC, the switch voltage stress is equal to the output voltage. In this paper, modified SIBC (mSIBC) is proposed with reduced voltage stress across active switches. The proposed mSIBC configuration is transformer-less and simply derived by replacing the one diode of the classical switched inductor structure with an active switch. As a result, mSIBC required low voltage rating active switches, since the total output voltage is shared into two active switches. Moreover, the proposed mSIBC required the same number of components compared to the classical SIBC. The Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) analysis, the effect of non-idealities on voltage gain, design methodology, and comparison of mSIBC are presented in detail. The operation and performance of the designed 500W mSIBC are validated through simulation and experimental work.

This paper deals with an active switched inductor network-based high gain boost converter. By using less number of components in circuit topology, a higher gain in voltage can be attained at a small duty cycle value by using the proposed converter, which helps in reducing the switch voltage stress and conduction loss. In addition, it draws continuous input current, has lower diode voltage stress, and lower passive component voltage ratings. The operating principles and key waveforms in Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) are presented. Parameter design, power loss calculation, characteristics, and comparative study with other non-isolated converters have been presented. Finally, a 200W hardware prototype is constructed and the viability of the proposed converter is verified through the experimentally obtained results.

In this article, a new transformer-less boost converter (TBC) is proposed to achieve high step-up voltage with a reduced voltage across switches. The proposed topology has the advantage of providing a high voltage gain, low voltage stress on the active switches, simplified control, and high efficiency. The structure is derived by modifying the classical switched inductor boost converter (SIBC) by replacing two of the diodes with a capacitor and a control switch, which results in a total output voltage equally shared by the two switches. Thus, the proposed converter needs a lesser number of diodes than the conventional SIBC, where the two active switches equally share the total output voltage and thereby reducing the voltage stress across the switches to half. Hence, low voltage rating switches can be used to design the proposed TBC structure. Also, a higher voltage gain is achieved using TBC without increasing the number of components of the existing SIBC. Furthermore, the proposed converter provides the common ground connection of source and load. The detailed analysis, effect of nonidealities, design, and comparison are presented. The experimental results of the proposed TBC are presented to validate its functionality and theoretical analysis.

The nanocrystalline bismuth oxide (Bi₂O₃) was produced utilizing a green combustion process with Mexican Mint gel as the fuel. The powder X-ray diffraction (PXRD) method proved the nanocrystalline nature and Bi₂O₃ nanoparticles (BONPs) in α phase and the average crystalline size of BONPs nanoparticles has been found to be 60 nm. The spherical-shaped structure with bright dot-like spots in the center of the selected area diffraction (SAED) is confirmed by the scanning electron microscopy (SEM) and Energy dispersive X-ray spectroscopy (EDAX) in conjunction with the transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) demonstrating the crystalline behavior of green NPs. The Kubelka-Monk function was used to analyze diffuse reflectance spectra, and the results revealed that BONPs have a band gap of 3.07 eV. When utilized to evaluate the photocatalytic capabilities of NPs, the direct green (DG) and fast orange red (F-OR) dyes were found to be activated at 618 and 503 nm, respectively. After 120 min of exposure to UV radiation, the DG and F-OR dyes’ photodegradation rate reduced its hue by up to 88.2% and 94%, respectively. Cyclic voltammetry (CV) and electrochemical impedance techniques in 0.1 N HCl were used to efficiently analyze the electrochemical behavior of the produced BONPs. A carbon paste electrode that had been enhanced with BONPs was used to detect the glucose and uric acid in a 0.1 N HCl solution. The results of the cyclic voltammetry point to the excellent electrochemical qualities of BONPs. Bi₂O₃ electrode material was found to have a proton diffusion coefficient of 1.039 × 10⁻⁵ cm²s⁻¹. BONP exhibits significant potential as an electrode material for sensing chemicals like glucose and uric acid, according to the electrochemical behavior.
