摘要：

Based on the conventional buck converter and the switched network, this study presents a new DC-DC buck-boost converter. The proposed buck-boost converter can realize high step-down gain when the duty cycle D is smaller than 0.414 and high step-up gain when D ranges from 0.414 to 0.5. Meanwhile, the proposed converter possesses continuous output current which makes the output filter unnecessary. Continuous and discontinuous conduction mode analyses are detailed presented. Finally, some SIMetrix simulations are implemented to verify the proposed buck-boost converter's effectiveness and feasibility.
