Abstracts:
[Objective］ Contactless power supply method, leveraging the advantages of no direct electrical contact between the primary and secondary side coils, is currently being explored in the rail transit industry. The high-power, high-frequency application scenarios pose challenges in the design of the contactless traction power supply system, component selection, and coupling mechanism design. It requires optimization of the design scheme and system efficiency. ［Method］ For rail transit application scenarios, the system structure of a contactless traction power supply system based on the LCC-S (inductance-capacitor-capacitor-series) compensation topology is introduced. A 250 kW contactless power supply system is designed, utilizing double D-shaped coils for the primary track coils and secondary receiving coils. The impact of factors such as mutual inductance of coupling coils and losses in magnetic materials on system efficiency is studied. System circuit model and coupling coil model are established. The system is simulated based on the model, and parameters for the magnetic core thickness in different regions of the secondary coils are optimized. An experimental platform for contactless traction power supply system is built, and tests are conducted at a power level of 250 kW to validate the effectiveness of the design optimization method. ［Result & Conclusion］ The simulation and experimental results confirm the effectiveness and feasibility of the design optimization method. Optimization of the core layout ensures coil mutual inductance and reduces core losses. The system demonstrates the capability of delivering a rated output power of 250 kW. Under air gap heights of 70 mm and 80 mm, the static and dynamic operating efficiencies of the system are both greater than 90%.
