摘要
介绍了一种双重三斜乘法型A/D转换器。该A/D转换器与采样保持技术、微机相结合在交流工频功率测量中的应用。且具有零点漂移小、稳定性好、成本低等优点。
This paper proposes a double three slope multiplying A/D converter
and introduces the new A/D converter application with sample/hold te-
chnique and microprocessor in the field of industrial power measurement.
The new A/D converter is of low price. The Watt meter based on the new
A/D converter and microprocessor is used now. And the precision is better
than 0.1%.
