摘　　要：针对电子设备故障诊断中要求高精度直流电压信号源问题,提出了一种全新的直流电压信号产生方法,它由直流电压信号产生环节、信号增益控制环节及输出信号反馈环节三部分组成,借助特定的补偿算法进行输出整定,实现了高精度的直流电压信号输出,具有工程实用价值。Aiming at high accurate DC signal source requirements in electronic equipment＇s fault diagnosis, a new method to generate it is presented. The design of three key components of DC signal output board is described as follow： signal generating link, gain control link, and output signal feedback link, and by adopting specific offset algorithm, the method rectified the output of DC channel. The application results show that this method can get a high accuracy DC signal output and may serve as the needs of engineering application.
