摘要
介绍了直流弧焊电源动特性的微机测试仪的原理、结构和微机研制过程中遇到的关键技术问题。测试仪可在1～2s内完成“空载—短路—空载”两种过程的动特性测试,并打印出曲线和数据。
In the paper, the principle, hardware, structure and the problems encountered in developing process of an apparatus are introduced which is used for the measurement of dynamic parameters of DC welding power source with the add of microcomputer. The apparatus has the functions to finish the total measurements in 1-2 seconds for the dynamic characteristics of power source from open to short circuit and reverse process, and the functions to print curves and data also.
