电动汽车电驱系统电磁兼容性能优化研究
Electromagnetic compatibility performance optimization of E-axle drive
摘要
Abstract
With the increasing adoption of electric vehicles,the electro magnetic compatibility(EMC)issues caused by high-frequency switching of power devices have become increasingly important.This paper analyzes the noise interference transmission path mechanism and establishes a conduction interference simulation model for the motor drive system.Closed-loop control is implemented based on the real vehicle control strategy using space vector pulse width modulation(SVPWM).An experimental test platform for conduction and radiation interference is constructed within an electromagnetic shielding chamber.By optimizing filtering,shielding,grounding,and loop design,the electromagnetic compatibility performance of the electric drive system is substantially improved.The results indicate that the optimized system exhibits significant enhancements in radiation emission,conduction current,and conduction voltage performance.This research provides robust data support for improving the electromagnetic compatibility performance of electric drives and offers valuable guidance for practical applications.关键词
