Analysis of electromagnetic interferences of electric machine in stratospheric information platform

It is very important to study the electromagnetic compatibility (EMC) of stratospheric information platform. A physical model of electromagnetic interferences (EMI) is developed based on electromagnetic radiation of sparkle discharge in electric machine. The EMI distribution and it's effect to communication antenna array in stratospheric information platform is computed and analyzed. The analysis results presented can be effectively referenced in the design of stratospheric information platform system.
