  In this paper, a new wide-input-wide-output non-isolated buck-boost DC-DC converter is presented. The proposed converter has continuous current and is able to buck and boost the input voltage with shorter duty-cycles of the power switch compared to conventional buck-boost converters. A smaller duty cycle for a given voltage gain translates to lower current ripple of the inductors, reduced conduction losses, alleviated voltage stresses of the semiconductor switches and improved overall efficiency. The proposed converter also benefits from a simpler structure and control scheme. In this paper, the steady state operation of the proposed converter is investigated under both continuous conduction mode (CCM). The simulation and experimental results confirm the validity of theoretical analysis as well as the proper performance of the proposed converter. Manuscript profile
