Novel Single Switch Quadratic Boost Converter with Continuous Input and Common Ground

High-gain voltage converters are crucial for various applications, including renewable energy systems and electric vehicles. Non-isolated converters are often preferred for small and medium power ranges due to their simplicity, ease of design, and cost-effectiveness. Boost-derived converters are particularly effective for such applications. While conventional quadratic converters provide high voltage gain, they are often limited by drawbacks such as a high component count, elevated stress levels, significant losses, and reduced efficiency. This paper introduces a novel quadratic boost-derived converter designed to address these issues. The proposed converter features a reduced component count, continuous input current, lower switching stress, common ground and reduced diode stress. Comprehensive operational details, steady-state analysis, and a comparative study with existing quadratic boost converters are presented. Experimental verification and validation confirm the superior performance and practicality of the proposed design.
