A Power Prediction Based Model Predictive Control Strategy for Dual Active Bridge Converters

Dual active bridge bidirectional DC-DC converter has the advantages of high power density and low switching loss. Recently, a predictive control technique, named moving discretized control set model predictive control has been introduced, in order to achieve faster dynamics and stable operation. But this strategy is rarely applied to DC/DC power converters. This paper proposes a model prediction control strategy based on the transmitted power for the case that the load on the secondary side is a DC power source, which can realise the bidirectional flow of power and has better dynamic response performance and steady state performance. The proposed control strategy is simulated on Simulink software. Simulation results demonstrate the effectiveness of the proposed scheme.
