Novel High-Gain Quadratic Buck-Boost Converter

Abstract

Based on voltage boosting technology, a simple new quadratic buck-boost topology is proposed. The proposed converter has higher voltage gain and uninterrupted input current, reducing the filtering requirements of the input port. The performance of the converter in uninterrupted conduction mode are introduced in detail, and the new quadratic buck-boost topology is compared with other buck-boost topologies with regard to voltage gain, number of topological elements, voltage stress and current continuity of switching devices, and the comparison showed its excellent characteristics. Finally, the experimental prototype of the new converter is developed by PSIM. The experimental data is tested under different conditions, and the record experimental data of PSIM to verify the excellent of the new topology.
