【摘要】：正在高端工厂自动化应用中(如油气厂和电厂),常会要求多路采集通道与通道之间进行隔离,其中高耐压、小尺寸、低EMI、高可靠性和低成本等要求在通道间隔离设计中别具挑战性。现有成熟方案,标准模块实现的通道密度往往仅限于四个通道或八个通道,通道间隔离只能承受数百伏特耐压。本文将提出一种替代性的高密度、易于设计的通道间隔离
[Abstract]:In high-end plant automation applications (such as oil and gas plants and power plants), multiple acquisition channels are often required to be isolated from each other, with high voltage tolerance, small size, and low EMI, Requirements such as high reliability and low cost are challenging in the design of interchannel isolation. In existing mature schemes, the channel density of standard modules is usually limited to four or eight channels, and the isolation between channels can only withstand hundreds of volts. This paper proposes an alternative high-density, easy-to-design isolation between channels
