摘要：

Due to the dual active converter, the various phase shifting angles in the transmitted power are coupled to each other. The result is that as the number of phase shifting angles increases, the flexibility of its control increases considerably. but so does the complexity of the control. this paper decouples the phase shifting angles in the transmitted power, thus providing a prerequisite for the multiple phase shifting in Model Predictive Control (MPC) later on. Firstly, the phase shift angle of the transmitted power is decoupled by replacing it with a new variable. Secondly. the MPC is applied after the decoupling in order to predict the future p states. -Hie substitution reduces the complexity of the operation and at the same time the error in the output is relatively small. Finally the correctness of the method is verified by means of simulation.
