Özet
This paper investigates a single-phase dual-active-bridge (DAB) DC-DC converter employing a sliding mode control (SMC) strategy for electric vehicle (EV) applications. To enhance dynamic performance and ensure stable operation, an SMC-based strategy is designed and implemented, and its effectiveness is evaluated under different operating conditions. The proposed approach integrates a solid-state transformer (SST)-based DAB converter, enabling high-efficiency bidirectional DC-DC power conversion. A mathematical model of the system is developed, and the corresponding control algorithm is designed and validated. Both transient and steady-state performance are analysed under various input voltage and load conditions. In addition, the SMC strategy improves system robustness against disturbances such as parameter variations, external perturbations, and unmodeled dynamics in the voltage regulation loop. All modelling, control design, and simulations are performed in the MATLAB/Simulink environment, widely used for power electronics and power system studies.
