Research on Dual Active Bridge Control Method for Model Predictive Control without Feedforward Compensation

Direct current transmission and distribution technology has been widely used in fields such as rail transit, new energy grid connection, and electric vehicle charging due to its high utilization rate of cable cross-section and low line loss. The DC converter is the core equipment for voltage conversion and power transmission. This article takes the dual active bridge (DAB) converter as the research object, and proposes a model predictive control without compensation to address the problem of long transient time response. Compared with traditional control schemes, this method has higher dynamic response ability because it eliminates the feedforward PI compensation link. Finally, simulation comparisons were conducted with other control schemes to verify the effectiveness of the proposed method.
