摘要：

The dual active bridge (DAB) converter is a popular topology with the ability of galvanic isolation and bidirectional power flow. In the practical application, there could be the significant transient current overshoot between the different operating conditions or in the start-up phase of the DAB converter. Therefore, a discrete-time model based model predictive control method is proposed in this paper to constrain the transient inductor current overshoot. An experimental prototype is also built to validate the proposed method. The experimental results are consistent with simulation waveforms and the transient current overshoot can also be effectively constrained to mitigate its stress on the switch devices.
