摘要
利用高精度有功电能和视在电能计量芯片ADE776 3设计了一款功率因数测量表 ,由于合理利用了ADE776 3集成的模拟和数字处理功能 ,简化了硬件和软件设计 ,加快了开发周期 ,降低了成本。同样由于很多功能都集中在单片芯片内实现 ,电路的稳定性也得以提高。此外 ,还介绍了测量原理 ,ADE776 3的工作原理 ,并结合ADE776 3对测量原理的误差从多方面进行了分析。
Based on high accuracy active and apparent energy metering IC ADE7763,a power factor meter is developed. Because of appropriate employment of the integrated analog and digital processing functions in ADE7763, hardware and software design is greatly reduced, development process is accelerated and cost is lowered. Also because many functions were implemented within a single IC, the circuit reliability is improved too. Furthermore, the measurement theory, the operating theory of ADE7763 are introduced and in conjugation with ADE7763, the measurement principle error is analyzed from several angles.
