"EMC for Product Designers, Fourth Edition" 是一本由Tim Williams编写的关于电磁兼容性(Electromagnetic Compatibility, 简称EMC)在产品设计中的应用的专业书籍。这本书主要分为三个部分,涵盖了法规标准、测试方法以及设计实践等关键知识点。 第一部分“法规与标准”详细讲解了EMC指令和相关标准。EMC指令是欧盟对电子设备电磁兼容性的法规要求,确保设备在电磁环境中不会受到干扰,同时也不会对外部环境产生过度的干扰。这部分可能包括了EMC指令的基本原则、实施细节以及国际和地区的相关标准,如IEC(国际电工委员会)和EN(欧洲标准)等。 第二部分“测试”涉及射频(RF)排放、抗干扰性及低频测试。RF排放测试关注的是设备在运行时产生的电磁辐射水平,以确保其符合限值要求,不干扰其他设备。抗干扰性测试则评估设备对来自外部电磁环境的抗扰度,例如电源线噪声、无线电广播或雷达信号等。低频测试通常涵盖电源线上的噪声和地线干扰等问题。 第三部分“设计”深入探讨了设计过程中应考虑的EMC问题。其中包括了干扰耦合机制,解释了如何通过不同的途径(如电容耦合、电感耦合和辐射耦合)传播干扰。布局和接地设计是减少干扰的关键,合理的电路布局可以降低信号间的相互影响,而良好的接地策略能有效地减少噪声并提供稳定的参考电压。数字和模拟电路设计章节可能涵盖各自的设计原则和注意事项,因为这两类电路对EMC的敏感度不同。接口和过滤章节则讨论了如何通过滤波器和保护电路减少信号传输过程中的噪声。屏蔽技术是防止设备内部和外部电磁辐射的重要手段,这部分会详细介绍各种屏蔽材料和结构。最后,系统级EMC讨论了整个系统的兼容性,包括子系统间的协调和整体解决方案。 这本书作为第四版,反映了自1992年以来EMC领域的最新发展和技术进步,对于产品设计师来说,是理解和解决实际工作中EMC问题的重要参考资料。书中包含的案例研究和实用建议有助于读者将理论知识转化为实际设计中的应用。

EMC for Product Designers, Fourth Edition Publisher:Newnes | Pages: 512 | 2007-03-28| ISBN 0750681705 | PDF | 6 MB Widely regarded as the standard text on EMC, Tim Williams' book provides all the key information needed to meet the requirements of the latest EMC Directive. Most importantly, it shows how to incorporate EMC principles into the product design process, avoiding cost and performance penalties, meeting the needs of specific standards and resulting in a better overall product. As well as covering the very latest legal requirements, the fourth edition has been thoroughly updated in line with the latest best practice in EMC compliance and product design. Coverage has been considerably expanded to include the R&TTE and Automotive EMC Directives, as well the military aerospace standards of DEF STAN 59-41 and DO160E. A new chapter on systems EMC is included, while short case studies demonstrate how EMC product design is put into practice. Tim Williams has worked for a variety of companies as an electronic design engineer over the last 25 years. He has monitored the progress of the EMC Directive and its associated standards since it was first made public. He now runs his own consultancy specialising in EMC design and test advice and training. * Includes the compliance procedures of the latest EMC Directive: 2004/108/EC * Short case studies demonstrating how EMC product design is put into practice. * Packed full with many new chapters including: - The R&TTE Directive and the Automotive EMC Directive looking at compliance aspects of radio and telecom terminal equipment and automotive electronic products - New chapter on military aerospace standards of DEP STAN 59-41 and DO1 60E - New chapter on systems EMC
