A Study on Software Triggering Method For Microcomputer Controlled SCR Welding Rectifier

Xuan Zhaozhi Jiang Lipei Liu Yuanchang (Jilin University of Technology)  
In this paper a software triggering method is discussed in detail for the microcomputer controlled SCR welding rectifier.The principle of the method presented is to make repeat timing in one of the CTC timing channels.This method has the advantage of simplified hardware and high dynamic responsib- ility.The adjustment job and the trigger circuits of the SCR welding mach- ine can be greatly simplified by using the software trigging method.The method can be applied to other SCR rectifying circuits controlled by microco- mputers.
