A novel single switch transformerless quadratic DC/DC buck-boost converter

A novel quadratic buck-boost DC/DC converter is presented in this study. The proposed converter utilizes only one active switch and can step-up/down the input voltage, while the existing single switch quadratic buck/boost converters can only work in step-up or step-down mode. First, the proposed converter is analyzed in steady-state. Then, its performance is validated using simulations in MATLAB/Simulink software. Finally, an experimental prototype is built for further verification.
