脉冲变压器的磁屏蔽

资料介绍
摘要:传统上, ANSI和IEC标准的要求,电表的磁场水平相对良性运作。在某些市场上,由于强大的稀土磁铁DC米篡改,可以使用的情况下更严格的要求不断涌现。本应用笔记介绍的方法来管理或抑制来自外部磁场对变压器用于Teridian公司/马克西姆71M6541 - 71M6545家庭的用电计量IC领域的影响。

Magnetic Shielding for Pulse Transformers
Introduction
The 71M654x family of electricity metering ICs are designed to be used with CTs or with shunt resistors that are
connected to 71M6xxx Remote Sensor Interfaces. These 71M6xxx Remote Sensor Interfaces are normally con-
nected to the 71M654x ICs via small low-cost pulse transformers.
Pulse transformers, just like CTs, can be influenced by external magnetic fields. Traditio……
