摘要
针对传统Buck-Boost输入输出电流断续的缺点,提出一种基于独立电感零纹波输入电流和输出电流连续的Buck-Boost变换器,详细分析了变换器的稳态工作原理。采用状态空间平均法,建立了变换器动态小信号模型,给出了小信号特征Matlab仿真波形。并对其进行交错并联优化,最后Saber电路仿真证明了理论分析的正确性。
A zero rippled input current and continuous output current Buck-Boost converter topology converter was proposed. The steady operation principles and small signal model by using the state-space averaging approach of proposed converter were presented in detail. The effect of the converter＇ s controller was analyzed by Matlab simulation of small signal properties. Then further optimization is for this converter by interleaving. The saber simulation has verified the theoretical analysis.
