Electromagnetic interference caused by electric load of more electric aircraft

  • 摘要: 多电飞机(MEA)电气系统越来越大量地采用电子变换器,使得电气系统内和系统间的电磁干扰(EMI)问题变得非常严重.基于MEA电气负载特性,将电气负载分为整流类、斩波类和逆变类,建模和仿真这3类主要电气负载在稳态和突加工作情况下的传导EMI电流,并对逆变类负载的EMI特性进行了实验验证.结果表明:负载对电源侧的EMI集中在电力电子器件开关频率及其倍频邻域;斩波环节后端连接的大功率电气负载的突加使电源线传导EMI特性发生明显变化,主要体现在幅度频谱极值所对应的频率上.研究结果对独立电气系统的EMI识别及滤波器设计具有指导意义.
