民用电子电度表设计

Design of A Civil Electronic Watt-Hour Meter

本文提出了一种民用的电子电度表的设计及其单元电路。讨论了简化的四象限乘法器的原理。本电路具有结构简单、成本低廉的优点,其性能完全符合民用电度表的要求。

In this paper, a civil electronic watt-hour meter was designed and its unit circuits were presented. The principle of simplified four-quadrant multiplier was discussed. The circuits have the advatages: simple structure and low cost. Their performance fits the requirement of a civil electronic watt-hour meter completely.
