  • Single input multi output converter based partial shading mitigation in solar photovoltaic systems

    • Novel current injection technique reduces mismatch losses under shading. • SIMO converter uses one input with multiple isolated outputs to improve energy transfer efficiency. • LEM sensors with Arduino enable real-time adaptive control. • Achieves uniform current distribution and 56 W output, outperforming TCT. One significant factor that influences the performance of photovoltaic (PV) systems is partial shading. When PV modules experience partial shading, they encounter mismatch losses that result in reduced power output. To address this issue, this study introduces a current injection technique utilizing a single input and multiple output (SIMO) DC-DC converter that provides electrical isolation. The effectiveness of this current injection method is evaluated on a 3 x 3 total-cross-tied PV array within the MATLAB Simulink environment and Experimental Setup. The SIMO DC-DC converter counteracts the impact of partial shading by injecting current into the array’s rows according to the mismatch current present in those rows. For the SIMO DC-DC converter, variable duty cycles for the gate pulses are generated based on the mismatch current in the rows. Performance metrics are used to compare the efficiency of the proposed current injection technique (CIT) with the traditional total-cross-tied configuration. Under shading patterns labelled case 2 and case 5, the CIT has demonstrated enhancements in output power of 90% and 80%, respectively. Overall, the CIT has improved output power by 65% compared to conventional total-cross-tied PV arrays.

  • A novel switched transformer-based microgrid system for energy conservation

    Energy Sources Part A Recovery Utilization and Environmental Effects, 2026
    The integration of hybrid energy systems plays a crucial role in promoting environmental sustainability. By leveraging renewable energy sources such as solar energy and fuel cells, and reducing reliance on fossil fuels, these systems significantly lower greenhouse gas emissions and minimize environmental impact. This study explores a grid-connected switched transformer designed to enhance power supply efficiency by reducing energy dissipation and generating less heat compared to traditional transformers used in linear power supplies. The research was conducted on a 1 kW photovoltaic (PV) system comprising four 250 W modules, a 100 W fuel cell, and batteries with a 50% state of charge (270 Ah, 72 V) to optimize energy conservation in a microgrid. All units are connected in parallel to a single DC bus via individual DC–DC converters. The proposed energy management strategy prioritizes solar PV and fuel cells as primary energy sources for the load. The system’s performance was evaluated under varying solar irradiation, load conditions, and scenarios with and without batteries. Utilizing the proposed switched transformer control technique (STON/OFFB), power losses were reduced by 50% and 68% compared to conventional control methods (STONNB and STONB).
