A Transformerless Switched-Capacitor Switched-Inductor High Gain DC-DC Converter

DC Microgrids will play a crucial role in the future as the world is experiencing a shift towards the renewable energy sector. A high gain boost converter with a low switch stress is proposed for Microgrid applications. The output voltage at the load is stepped up using the redesigned switching inductor. The suggested boost converter offers a larger voltage gain than standard boost converters. The converter has only one switch and is controlled by a single control system, which reduces the circuit's complexity. Continuous conduction mode (CCM) and discontinuous conduction mode (DCM) are used in the steady-state analysis (DCM). Other recent and similar topologies are compared to the suggested topology. Theoretical Loss Analysis is performed, and the influence on the converter's efficiency is evaluated. All experimental results and mathematical analysis are verified with the help of the hardware prototype developed.
