摘要
飞机航空电子系统设备级滤波电路对系统的正常工作有重要作用,从中选取28V直流电源滤波电路作为典型电路,结合印制线路板(PCB:Printed circuit boards)图,基于计算机仿真技术(CST)对其进行场路协同仿真;最后通过矢量网络分析仪对实际滤波电路进行了共模和差模插入损耗测试,验证了场路协同仿真的正确性,并通过实验和仿真得出每种类型的电气元器件对共模和差模插入损耗的贡献。
Equipment level filter circuit of a certain aircraft avionics system plays an important role in the normal operation of the system.28VDC power supply filter circuit is selected as a typical circuit,which is combined with PCB printed circuit board diagram to conduct field and road co-simulation based on CST.Finally,the common mode insertion loss and differential mode insertion loss of the filter circuit are tested by the vector network analyzer to verify the correctness of the field-circuit co-simulation and the actual test,and the influence of each type of electrical components on common mode insertion loss and differential mode insertion loss is obtained through experiment and simulation.
