摘要
Abstract
A high-precision digitally-controlled constant current power supply has been proposed in this paper,which takes DSP as the control kernel,and the integrated operational amplifier LF356 as the deep negative feedback sys-tem. PID control algorithm has been introduced to adjust the output setting current in time. The buttons are taken to preset the step value and LCD is adopted to display the actual measuring value. Test results indicate that the proposed system has a high output current precision and better reliability,which make it a valuable choice for theapplication with high power and constant current.关键词
