模块化均衡拓扑及控制策略研究
Research on the Modular Equalization Topology and Control Strategy
摘要
Abstract
The equalization of the cells connecting in series can improve the battery life and energy utilization.The active equalization scheme based on the energy transfer inductor has the advantages of simple structure and is easy to control.It is widely applied in the engineering practice.Modular extension of the equalization circuit based on the inductors was done.The permutation and combination of the equalization units could generate multiple kinds of equalization circuit.The working priciple of the generated equalization circuits was analyzed.The comparisons of the circuits were given and the corresponding control strategies were discussed.A general PWM control strategy was proposed,which was simple and high portability.It was applied to all the circuits generated by the equalization units.The simulation and experimental results show that different equalization has different applications.The proposed control strategy can realize active equalization effectively.关键词
