TI AMC1304智能电网电流电压检测方案
TI公司的AMC1304是精密Delta-Sigma (ΔΣ)调制器,输出和输入通过容性绝缘层隔离,满足UL1577和VDE V-0884-10标准,隔离电压高达7000 VPEAK输入电压测量范围±50-mV或 ±250-mV ,CMOS或LVDS数字接口,主要用于工业马达驱动,光伏逆变器和能量电表.本文介绍了AMC1304主要特性,简化电路图,以及电流检测单元TIDA-00080主要特性,绝缘电流/电压模块(ICVM)和滤波器模块(FMB)系统框图,电路图,材料清单和PCB设计图.
The AMC1304 family are precision, delta-sigma (ΔΣ) modulators with the output separated from the input circuitry by a capacitive isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation of up to 7000 VPEAK according to the UL1577 and VDE V-0884-10 standards. Used in conjunction with isolated power supplies, the device prevents noise currents on a high common-mode voltage line from entering the local ground and interfering with or damaging sensitive circuitry.
