SCR Circuit Driven By Trigger

Published:2011/5/12 9:31:00 Author:Robert | Keyword: SCR, Trigger | From:SeekIC

The unijunction transistor Q1 is used as the clock for the relaxation oscillator to drive one trigger of the 7473 double triggers. The output Q is used to trigger the SCR so that the power voltage can be chosen freely according to the application. But it can not exceed the rated voltage of SCR.
