Review and Perspective of System-Level EMC Technologies

Lei J

Abstract

System-level Electromagnetic Compatibility(EMC)problems must be encountered in the life cycle of information equipments.If it can not be solved correctly,a lots of development outlay will be wasted.Sometimes,the information equipments will be useless.In this paper,based on review and perspective of system-level EMC technologies,novel methods namedtop-down,systemic,EMC quantificational pre-designandbehavioral level simulation of systcm-lcvel EMCare presented and commended for aircraft EMC design.The perfect system EMC performance can be achieved by evaluating EMC performance,distributing the EMC parameters quantificationally,optimizing design time after time.In addition,the system EMC performance can be analyzed along with the change of subsystem parameters.The subsystem parameters can be adjusted to meet the system EMC performance as well.The potential EMC problems can be exposed at the stage of design and resolved before the design is finalized.Meanwhile,system-level EMC test technologies are prospected.
