Urgent (for a project):
How to trigger an scr at a specific angle and without any manual intervention?(i.e. we just need to use some variable component and the angle would change accordingly)...is it possible to use 555 timer in monostable mode and generate a trigger??...is it possible to change the firing angle if i use 555??..pls reply soon...i m planning to make a full wave bridge rectifier using scrs...pls give a ckt diagram for the trigger ckt if possible...also once i trigger the scr, will get completely off in the negative half cycle of the supply voltage?...the attached figure is the ckt diagram of what i m planning to make..
