AMT控制器电磁发射干扰特性研究OACSTPCD

Based on the electromagnetic emission requirements for military equipment and subsystems in GJB151B-2013,and by taking a certain model of AMT controller as the research object,the electromagnetic emission interference characteristics of AMT controller is analyzed,and CE102 power line conducted emission test and RE102 electric field radiation emission test are conducted.The experimental results show that the power line conducted emission and electric field radiation emission of the AMT controller used in the experiment can meet the electromagnetic emission requirements of GJB 151B-2013.The electromagnetic conducted emission of the power line positive and power line negative are basically the same,and there are multiple harmonic interferences with 50 Hz as the fundamental wave.The safety margin is the smallest at 50 Hz,about 10 dBμV.The electromagnetic radiation of the AMT controller after shielding treatment is basically consistent in both vertical polarization and horizontal polarization antenna states.To further improve the safety margin of electromagnetic emission interference in AMT controllers,multiple harmonic interference suppression measures with 50 Hz as the fundamental wave should be taken at the power line port,and meanwhile the further shielding and protection measures should be taken for the holes,interfaces,and cables on the AMT controller.
