Hi all!
I'm currently designing a project which is to build a SCR firing circuit with 24VAC, 50HZ supply, and the output requires to have a delay of triggering (alpha) that can be controlled from 0~180 degrees.
I'm thinking of using a 555 timer to generate pulses at 50HZ, but I don't get it very much. I saw some suggestions such as TCA785, too, but I'm not sure how to use these chips.
Could someone give me a hint please?
