摘要：
Given the existing DC-DC converter applications and needs, to further improve the voltage doubling technology, taking the boost converter with coupled inductor structure as the research object, its working principle is analyzed and the voltage doubler unit is reconstructed. This structure ensures the voltage doubler while suppressing the current impact in the switched capacitor and clamps the coupled inductor. The DC voltage doubling unit is applied to the traditional Boost converter. On this basis, a new family of Boost and Buck-Boost converters was deduced. A specific topology with this structure was selected, the working principle and steady-state characteristics of the converter were deeply studied, and various performance indicators in CCM mode and DCM mode were compared and analyzed. Theoretical a-nalysis verifies the high efficiency and high gain of the converter characteristics, and simulation verification is implemented. A 150 W experimental prototype is built and verified by experiments. © 2022 Editorial Department of Electric Machines and Control. All rights reserved.
