摘要
基于ATMEL公司的AT89S52新型数字控制的直流电流源,区别传统的模拟控制直流电流源,数控直流电流源输出电流范围宽,控制、测量精度高以及纹波电流、噪声小,是今后恒流源研究的一个热点。
A This research studies the new digital control DC current source based on ATMEL＇s AT89S52. Being different from the past, the digital control DC current source improves the output current range, improving the accuracy of control and measurement, and reducing the ripple current and noise. Therefore, digital control DC current source is hot for future study of constant current source.
