A Non-Isolated Voltage Lift Based Enhanced Quadratic Boost Converter

This paper presents a novel Voltage Lift based Enhanced quadratic boost converter (VLEQB) topology that enhances the voltage gain by incorporating a voltage lift technique. The proposed configuration achieves higher output voltage by employing a parallel charging and series discharging for the inductor-capacitor cell. This approach offers several advantages, including input-to-output Common ground and the ability to maintain continuous input current (CIC), making it suitable for renewable energy applications.A detailed analysis is conducted on the VLEQB converter's steady-state operation in continuous conduction mode (CCM). A comprehensive comparison with existing related topologies is carried out to highlight the unique features and potential benefits of the VLEQB converter. Furthermore, simulation results obtained using the PSIM platform for a <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$40 / 400 ~\mathrm{V}, 500 ~\mathrm{W}$</tex> Converter validate the theoretical analysis, demonstrating strong agreement between simulated and theoretical findings.
