| 總結: | For isolated DC-DC converters in EV battery charging systems, efficiency and dependability are crucial. This paper presents a redundancy-based fault-tolerant control strategy for Dual Active Bridge (DAB) converters to enhance reliability and efficiency in isolated DC-DC applications, such as EV battery charging systems. The proposed method addresses open-circuit failures in Insulated Gate Bipolar Transistors (IGBTs) by integrating backup switches that activate seamlessly during faults, ensuring uninterrupted power flow. The system's performance was validated through simulations, demonstrating effective fault mitigation, minimal power disruptions, and enhanced operational stability. This research highlights the potential of redundancybased fault-tolerant designs for future hardware implementations in high-reliability energy applications. © 2024 IEEE. |
