三重移相控制下DAB变换器全局优化控制策略及分析
Global Optimized Control Strategy of Dual Active Bridge Converter Controlled by Triple-phase-shift Modulation Scheme and Its Analysis
摘要
Abstract
By analyzing the equivalent circuit of the dual-active-bridge (DAB) controlled by TPS scheme,the general relations between the transferred power and the control variables as well as the relations between the RMS value of the inductor current and the control variables were derived.Therefore,the DAB operation can be divided into six modes.Moreover,by investigating the influence of the perturbation of control variables on the transferred power and the RMS value of the inductor current,the global optimal conditions can be deduced.Then the optimization problem for different conditions can be unified.In addition,it can be concluded that the solutions of the global optimal conditions are the optimal control method to minimize the RMS value of the inductor current.Finally,a prototype of DAB was built,and the experimental results verified the validity of the theoretical analysis and the effectiveness of the proposed modulation scheme.关键词
