ST STEVAL－IPE014V1智能传感器电表解决方案

ST公司的STEVAL-IPE014V1是智能传感器STPMS2的演示板,设计和姐妹片STPMC1的STEVAL-IPE010V1演示板一起用于能量表.而STPMS2是一款智能传感器,采用Rogowski线圈,电流变压器,霍尔或分流传感器来测量动力线系统的能量,VCC电压3.2V-5.5V,集成两两个二阶sigma-delta (ΣΔ)调制器,支持50-60 Hz, EN 50470-1, EN 50470-3, IEC 62053-21, IEC 62053-22等标准,适用于电表,马达控制,工业过程控制,称重表和压力传送器.本文介绍了STPMS2主要特性,方框图和应用电路图,以及STEVAL-IPE014V1演示板特性,电路图和材料清单.

The STPMS2, also called “smart sensor” devices, are ASSPs designed for effective measurement in power line systems utilizing Rogowski coil, current transformer, Hall or shunt sensors. These devices are designed as building blocks for single-phase or multi-phase energy meters along with the STPMC1 device, a digital signal processor designed for energy measurement. This device can be used in medium and high resolution measurement applications where single or double inputs must be monitored at the same time. The STPMS2 are mixed signal ICs consisting of an analog and digital section. The analog section consists of a programmable gain, low noise choppered amplifier, two second-order ΔΣ modulator blocks, a band-gap voltage reference, a low-drop voltage regulator and DC buffers, while the digital section consists of a clock generator and output multiplexer...
