yes mehmood i know that and i have make several circuits but they do not gave output stabilized. I use 200V pulsating DC but i cannot able to fire SCR below 50V and i also have limitation that if SCR trigger before ending 10% then my system will be damaged.
Is there any modified from standard RC+Diac circuit which fire SCR at specific angle and will always trigger at ending 5-10%.
Thanks!
