摘要

本文提出了一种新型的抽头电感双向降压/升压(TI-B-buck/boost)拓扑，克服了非隔离型双向DC-DC (BDC)传输比限制在小范围内的缺点。本文详细分析了TI-B-BUCK/BOOST的原理和特点。然后，基于新拓扑的功率损耗模型，对抽头电感的匝比进行了优化。基于MATHCAD的计算机仿真和实验室样机的实验结果表明，TI-B-BUCK/BOOST大大提高了非隔离式BDC的传输率，其效率远高于传统的双向BUCK/BOOST。

A novel tapped inductor bi-directional Buck-Boost topology

This paper proposes a novel tapped-inductor bi-directional buck/boost (TI-B-buck/boost) topology, which can overcome the drawback of non-isolated bi-directional DC-DC (BDC) that its transfer ratio is restricted in a small range. This paper analyzes the principle and characteristics of TI-B-BUCK/BOOST in detail. Then, the optimization of the turn ratio of tapped-inductor based on power loss model of the new topology has been done. Computer simulation based on MATHCAD and experimental result on a prototype built in lab verify that TI-B-BUCK/BOOST widely extends the transfer ratio of non-isolated BDC and its efficiency is much higher than conventional bi-directional BUCK/BOOST.
