Optimization Method of Current Stress and Backflow Power of DAB Converter Based on Dynamic Matrix Control
Aiming at the current stress and the backflow power problems of dual active bridge (DAB) converters with dual-phase-shift control
this paper establishes the weight optimization function of the current stress and the backflow power. Its design principle is to ensure the current stress suppression effect and reduce the backflow power at the same time. The optimization selection process of the weighting factor is analyzed to obtain the inner and outer phase-shift ratio of the DAB converter in two working modes. In order to improve the dynamic response performance of the output voltage of the DAB converter and improve the load adaptability and robustness
this paper proposes a voltage predictive control method based on dynamic matrix control (DMC). Finally
by combining the StarSim real-time simulator and DSP chip
a half-physical experimental platform for the DAB converter is built. The experimental results verify the effectiveness and correctness of the proposed control strategy in improving the dynamic response performance of the DAB converter voltage
suppressing the current stress and reducing the backflow power.
