Photovoltaic (PV) arrays are often affected by partial shading (PS), which can significantly reduce their power output. Dynamic reconfiguration is a promising technique for mitigating the negative effects of PS by adjusting the electrical connections of the PV modules in real-time. This paper introduces a hierarchical-based switching block scheme for the dynamic reconfiguration of PV arrays under PS conditions. With the aim of mitigating the negative impact of PS on PV arrays, the proposed system employs a low complexity and easily scalable architecture, making it well-suited for practical applications. Comparative assessments against conventional configurations such as bridge-linked (BL), total-cross-tied (TCT), and series–parallel (SP) reveal superior energy harvesting efficiency for the proposed system under various shading conditions. The hierarchical switching block architecture, featuring multiple levels of switching blocks, enables efficient and flexible reconfiguration of the PV array, even in the presence of complex shading patterns. Through extensive simulations, the system consistently outperforms conventional configurations by adapting effectively to changing shading patterns and optimizing the PV array’s output. The proposed switching block (SB) reconfiguration technique significantly outperforms existing methods like TCT, Sudoku, dynamic proposals, and Magic Square in terms of both power generation (up to 42.52% increase) and efficiency (up to 42.13% improvement) under diverse partial shading conditions. The proposed hierarchical-based switching block scheme thus presents a promising solution for enhancing the dynamic reconfiguration of PV arrays under PS conditions, offering a balance between low complexity, scalability, and superior energy harvesting efficiency for practical applications in the realm of solar energy.

Step-up converters find extensive application in various sectors, including powered vehicles, photovoltaic systems, continuous power supplies, and fuel cell systems. This paper describes the process of designing and building a resistive load step-up (boost) converter, which is a widely used industry application for increasing the direct current (DC) input voltage. This study focuses on ascertaining the appropriate values for the inductor and capacitor within the circuit. The design primarily emphasizes continuous mode operation, involving varying voltage inputs of 10V and 20V DC, while employing a switching frequency input of 25 kHz with the IGBT serving as the switching device. The design evaluation of this circuit aims to regulate the input voltage to support a stable output voltage of 30 VDC, with a simulation power conversion efficiency of 96.18 percent for the input voltage,10V, and a simulation power conversion efficiency of 96.08 percent for the input voltage,20V. This examination also incorporates the requirement of a ripple inductor current, which should not exceed 25% of the total inductor current, and an output voltage ripple is less than 1%. The circuit design parameters are determined based on factors such as output voltage, inductor voltage, and inductor current waveform. MATLAB Simulink software will be used to check the circuit design, thus confirming the agreement between simulation results and theoretical predictions. The simulation results provide compelling evidence that the established model proficiently maintains the output voltage under diverse input voltage scenarios. As a result, these parameters are suitable for the construction of a fully operational boost converter circuit. This paper systematically presents all objectives, calculations, experiments, data, and results in a comprehensive manner.

Similar to any solar conversion application into electrical power, the photovoltaic panel performance is suffering from the high temperature and when it is mounted in hot-dry climates. One method to overcome these setbacks is to marry the PV panel with a solar air updraft system, which led to a decline in its temperature by upgrading the air mass flow facing the PV-panel. This paper presents a comprehensive review of the hybrid Photovoltaic-Air Updraft Solar models. The review presents and discusses the compounds and experimental and theoretical studies that were carried out on the existing PV-solar air updraft models. In addition, the paper proposed a new solar air updraft technique by coupling the PV panel with a swirling air generator. The proposed model is simple and more efficient than the conventional solar air updraft design, leading to higher PV panel cooling performance.
