The invention discloses a model predictive control DAB converter and device based on a fundamental wave modulation strategy, and aims to solve the problem that in traditional control of the DAB converter, when the load of the DAB converter suddenly changes, control parameters of traditional closed-loop control are possibly not suitable for new working conditions any more, and consequently a system is unstable. Model predictive control is applied to the DAB device, so that the dynamic performance of the DAB converter can be better improved. 本发明公开了一种基于基波调制策略的模型预测控制的DAB变换器及装置，针对于在DAB变换器的传统控制当中，当DAB变换器发生负载突变时，传统闭环控制的控制参数可能不再适合新的工况，从而造成系统的不稳定的问题，将模型预测控制应用于DAB装置可以更好的提高DAB变换器的动态性能。
