摘要:
本文通过分析PCB电路辐射EMI噪声产生的机理,建立了PCB差模辐射干扰模型和共模辐射干扰模型. 介绍了通过近场探头和频谱仪进行辐射EMI噪声溯源的原理和操作方法,可大致确定辐射噪声源的位置. 提出了通过场探头大致确定辐射源后,根据辐射发生模型,结合辐射源的器件、线路特点制定辐射噪声抑制方案的整改思路. 本文运用以上思路针对吸痰器的辐射EMI问题进行整改分析,并通过德国罗德施瓦茨(R&S)建造的3 m法标准电波暗示进行辐射检测,验证了本文针对医疗设备辐射EMI问题提出的整改思路和整改措施的有效性.
Abstract:
Based on the analysis of the mechanism of EMI noise generation in PCB circuit,the PCB differential and the common mode radiation interference model are established. This paper,by using the near field probe and the frequency spectrum instruments,presents the principles and operational methods that can determine the EMI radiation noise sources and roughly their corresponding positions.?After the rough position of radiation source is determined by the field probe,and the radiation source device,and the?circuit characteristics with the radiation model are combined,the thread of the radiation noise suppression program is developed. This paper with above ideas proceeds with the correctional analysis as regard to sputum aspirator,and subsequent radiation test by standard 3 m anechoic chamber built by German company R&S,proves the effectiveness of the correctional plans and approaches presented in this paper.
