Hello,
I'm working on Proteus to build SCR triggering circuit and then put some example loads; like, a motor.
I actually don't have a deep understanding of power electronics, I know they are used to big electronic control; like controlling heavy machines that need variable AC voltage.
Of course there are a lot of other applications; they are used in power transmission, heavy drills, compressors, ac motor control, energy conversion, UPS ... etc.
I'm really interested in doing a starting project; like controlling ac motor speed.
But on the web, there are various examples of circuits that driver SCR for a certain purpose. I don't know where to start, I built some examples on Proteus, but when the simulation crashes I realizes that I don't know what I'm doing and why I'm doing it, when I try to modify the circuit I know that I don't know how it works in the first place.
Here's my efforts to do something:
