Biomechanics-inspired transformation and optimization plan for new energy vehicle transformers

Abstract

This study aims to deeply analyze a fault-tolerant LLC resonant DC-DC converter through biomechanical inspiration and explores its application in electric vehicle charging systems. Through advanced control strategies and optimized designs, the efficiency and reliability of the converter are significantly improved, while grid disturbances are reduced. The proposed current feedforward control and direct power control methods enhance the performance of the converter. Experimental and on-site tests demonstrate that the designed converter operates efficiently and stably at high power levels, with the ability to tolerate grid voltage fluctuations. During the design process, we introduced the concept of biomechanics to improve the intelligence and adaptability of the converter. First, by imitating the adaptive ability of biological systems, the converter can adjust operating parameters in real time to cope with changing grid conditions and load demands. Second, by learning from the efficient energy utilization mode in nature, the energy conversion process is optimized to minimize energy loss. bIn addition, the fault tolerance mechanism of biological systems is learned, and redundancy and fault detection functions are designed to improve the overall reliability of the system. The integration of this converter with smart grids enables demand response management, optimizes grid load distribution, and reduces charging costs. A universal interface has been developed to accommodate different charging standards, and the modular design enhances market adaptability and user convenience. The integration of an intelligent charging management system enhances charging efficiency and user experience, achieving dynamic matching with electric vehicle battery status, grid load, and user demands. This study provides innovative ideas and solutions for electric vehicle charging technology, driving the development of the new energy vehicle industry and laying the foundation for future charging technology innovations. By combining the inspiration of biomechanics, the intelligence and adaptability of the converter are further improved, which points the way for the future development of the electric vehicle charging field.
