| 摘 要： | 多重化双向Buck/Boost变换器常作为能量交换接口用于储能系统中。采用基本建模法对三重化双向Buck/Boost变换器建立交流小信号模型,基于变换器的开环特性,设计了电压、电流补偿网络,在此基础上提出一种新的基于前馈校正的复合双闭环控制策略。为验证所提控制策略的正确性进行了MATLAB仿真研究。仿真结果表明:该控制策略可为三重化双向Buck/Boost变换器提供良好的动、稳态性能,同时对大范围的负载变化等扰动均具有很好的鲁棒性。

| Abstract: | Multichannel bidirectional Buck/Boost converters, served as energy exchange interfaces had often been used in energy storage systems. The basic modeling method was used to build small signal AC model for threechannel bidirectional Buck/Boost converter. Base on the open loop characteristic of the converter, the voltage and current compensation network were designed, following this, a new double closedloop control strategy based on feedforward correction was proposed. The paper adopted the MATLAB simulation research to prove the correctness of the proposed control strategy. The Simulation results showed that the control strategy could provide good dynamic and steadystate performance for the threechannel bidirectional Buck/Boost converters, and at the same time, it demonstrates good robustness which could adapt to wide range of load variation. |
