摘　　要：针对级联H桥(CHB)双向变换器+双向全桥(DAB)DC/DC变换器拓扑的电能路由器,提出一种新的控制策略,即基于空间矢量脉宽调制(SVPWM)的交流侧电流预测控制和基于二分查找寻优的直流侧输出电压预测控制,在提升系统动态性能的同时,也避免了传统预测控制方法计算量过大和开关频率不固定导致的纹波较大问题。最后,基于Matlab/Simulink进行仿真分析,并通过实验验证了该控制策略的正确性和有效性。A new control strategy is proposed for the electric energy router of cascaded H-bridge(CHB)bidirectional converter and dual active bridge(DAB)converter.This control strategy is the AC-side current predictive control based on space vector pulse width modulation(SVPWM)and the DC-side output voltage predictive control based on binary search optimization.While improving the dynamic performance of the system,it also avoids excessive calculation of traditional predictive control and large ripple caused by the unfixed switching frequency.Finally,Simulation is built based on Matlab/Simulink,and the correctness and effectiveness of the control strategy are verified by experiments.
