电驱动系统带载工况下电磁干扰试验
Experimental study on electromagnetic interference of electric drive system based on load condition
摘要
Abstract
This paper employs the self-developed electromagnetic compatibility test system to conduct the experimental research on electromagnetic interference based on the load condition,studies the electromagnetic interference characteristics of electric drive system under multiple conditions,conducts the experimental research on high and low voltage power-up conduction emission.Our results show high voltage power-up forms serious coupling interference to the low voltage system.The experimental research on radiation emission and high voltage conduction emission under the load condition is conducted,which reveals the electromagnetic interference of radiation emission and high voltage conduction emission with load is significantly higher than that of no-load,and the law of the electromagnetic interference value gradually increases with the increase of the speed.Combined with the experimental research,the EMI simulation model of high voltage conduction of an electric drive system is verified under load conditions.Our results show in the frequency band of 9 kHz～30 MHz,the conduction emission simulation and test spectrum of the electric drive system under various load conditions have good consistency,and the resonant point error is under 6 dB,which validates the accuracy of the simulation model.关键词
