中文摘要

本文设计了一种用于串联电池组的双层硬件拓扑,实现了模块内及模块间电池单元的同步能量转移。底层采用总线型飞跨电感结构,通过插入死区时间减少MOSFET发热。结合改进的模型预测控制器,有效调度均衡电流,提升了电池组的一致性与能量利用效率。

English Abstract

This article designs a dual-layer hardware topology for series battery packs to realize the synchronous energy transfer among cells in the same module and cells across different modules. A bus-type flying-inductor structure is employed as the bottom-layer functional block, with sufficient dead-time gaps inserted between switches to mitigate mosfet heating caused by short-circuits. In order to main...
