Thanks for the circuit but I guess your ckt is very complicated , the object is not too difficult , its just to get the full wave rectification through SCRs and then connecting an inductive load to it (i want to use 12V DC Motor) , i am attaching its basic ckt diagram but i wonder how to control the SCRs using its Gate. It should have a seperate circuitry which is required ! . I have tried my own by short circuiting the 2 Gates of SCRs and then connecting a seperate UJT circuit with it that turns ON GATE but it doesn't work. If you have some proper circuit for it that is already been TESTED then pls fwd it , thanks bro !
