针对传统DC-DC变换器存在电压增益低
电压应力高
硬开关、二极管反向恢复大等问题
该文提出带有谐振软开关的高增益耦合电感Buck-Boost变换器。该变换器是将C-L-VD-C单元、有源钳位支路、耦合电感倍压单元以及谐振电容、输出电感加入到Buck-Boost变换器得到。通过C-L-D-C单元、耦合电感倍压结构实现高电压增益。构建电容-电感回路
实现低输出电流纹波。通过有源钳位支路可使所有开关管都工作在零电压开关(ZVS)条件下。通过LC谐振实现所有二极管的零电流关断
减小因二极管的反向恢复特性造成损耗
提出变换器的拓展结构。对变换器性能进行详细的分析
给出实现软开关的临界条件。搭建一台150 W的样机
对变换器进行理论分析的验证。
This paper proposes a high-gain coupled inductor Buck-Boost converter with resonant soft-switching to address the low voltage gain
high voltage stress
hard switching
and significant reverse recovery of diodes inherent in traditional DC-DC converters. The converter is realized by integrating the C-L-VD-C unit
active clamp branch
coupled inductor voltage-doubling unit
resonant capacitor
and output inductor into the Buck-Boost converter. High voltage gain can be achieved through the C-L-D-C unit and the coupled inductor voltage-doubling structure. A capacitor-inductor loop is established to achieve low output current ripple. The active clamp branch allows all switches to operate under zero-voltage switching (ZVS) conditions. Zero current turn-off of all diodes is realized through LC resonance
reducing losses caused by the reverse recovery characteristics of the diodes
and an extended structure of the converter is proposed. A detailed analysis of the converter’s performance is conducted
providing the critical conditions for achieving soft-switching. A 150 W prototype was built to verify the theoretical analysis results
