摘要：为了提高电子产品抗干扰能力,研究了电快速瞬变脉冲群(EFT)试验中信号共模性质和接地方式对提高电磁兼容(EMC)能力的影响,结合设计实例分析了抗干扰措施。EFT试验表明,电子脉冲群干扰信号的能量积累,可能是电子产品产生故障的重要原因之一,规范试验方法和正确选择接地方式是保证试验成功的前提。
To improve the anti-interference capability of electronic product, this paper describes the influence of improving the ability of Electro Magnetic Compatibility (EMC) by the common-mode character and grounding mode in Electrical Fast Transient (EFT) testing. The measure of anti-interference based on the design is offered. The EFT testing indicates that energy accumulation of EFT may be one of the important reasons leading electronic product to failures. The standard testing method and the proper grounding mode are the precondition of a successful testing. The study on the sensibility of EFT testing should be developed presently.
