摘要
介绍了一个在 PC/ 10 4总线基础上采用数字闭环技术实现的交、直流精密程控电源 ,详述了组成数字闭环的硬件原理框图和 PID控制算法。该程控电源轻便 ,可完成电压表、电流表的现场检定 。
A precise AC/DC programmable source based on PC/104 bus and digital close loop is introduced. The hardware diagrammatic layout and PID control algorithm are presented in detail. The programmable source is portable. It can be used to test voltage meter and current meter or other electrical device cooperating with other standard device in situ.
