Research And Design Of An Electromagnetic Compatibility Of Shipborne Electronic Equipment

Electromagnetic compatibility is an inherent performance of electronic equipment,is given in the product design, electromagnetic compatibility design directly affect theproducts to function properly in its intended electromagnetic environment. However, thefunction of the different products index design, electromagnetic compatibility design bymany uncertain factors, it is difficult to do quantitative design and to ensure a successfuldesign can only be done early in the product design as much as possible to address andconsider the issue, reduce late rectification and improved, with the greatestcost-effective the solution of electromagnetic compatibility problems. In this paper, aNavy shipboard communication equipment is issued. Design of the electromagneticcompatibility of electronic equipment is discussed.First, the electromagnetic environment of the electronic devices in which theanalysis and combine related to electromagnetic compatibility standards and normsEMC product design needs.Secondly, according to the characteristics of the device itself, the analysis of theEMC design characteristics and difficulties. How to reduce the equipmentelectromagnetic interference (EMI), and how to enhance the device anti-jammingcapability (EMS) and how to reduce the electromagnetic interference path couplingthree to start on three elements starting from electromagnetic interference. Key circuitof the power supply, transmitter, receiver, etc. on the device, the analysis process of theelectromagnetic compatibility, and the shield body, the aperture processing, the cablelayout connector choose the design of the electromagnetic compatibility. Round to takemeasures to improve the electromagnetic compatibility.Finally, according to the new measures of the previous EMC electromagneticcompatibility of equipment is verified, summarize and EMC equipment in theequipment early design some effective methods and measures, I hope these methods andmeasures of certain reference significance for practical engineering applications.
