摘要
恒流源在现代工农业及科研生产的运用中正朝着体积小、精度高、稳定性好、使用灵活的方向发展。文章就压控恒流源的技术和原理进行了分析,提出了使用功率运算放大器获得高稳定恒流源的技术方案,并使用Pspice进行了较为详细的模拟和理论分析。
The constant current source, which used in industry, agriculture and science production, has been paid close attention to smaller bulk, higher precision, more steady and flexible in use. This paper analyes the theory and the technical approach of voltage controlled current source, presents a technical plan of highly steady constant current source based on the power operation amplifier, and simulate its application via Pspice.
