Hello sir ,i am usin 4 SCR in bridge configuration.and i have to use both resistive as well as inductive load.
i am using zero crossing detector to create the firing pulse and applied it to interrupt.i am using pic16f877a ic.
to vary the firing pulse i am using a variable pot of 0-5 volts which...
Hello everyone.I am doing my project Microcontroller based firing angle control of Scr .for this i am using Analog input 0-5volt ,a ZCD as interrupt ..but i am unable to do programming plz help anyone ..i know the logic but i am not able to write the code ..plz help me
Sir i trided everything on proteus..can you plz tell me the idea about circuit.sir i tried so many times i search on google but found nothing if possible plz suggest me .plz send me the circuit .
Re: urjent response require firing angle ontrol
sir refer this.i have used all thad ZCD ADC and varying pulses but not able to get output plz help .i had attached the proteus file and hex file plz run and observe.

sir please see the attachment i added the proteus simulation and hex file also.sir at the output i am getting varying pulses but at isolatoin stage i am getting nothing plz see what is the actual problem plz solve sir.i am not geeting gate pulses for the scr.i have also tried pulse transformer...
Sir i have try all this .optocoupler ic moc302 pulse transformer but not getting output.at the output of microcontroller i am getting varing pulse having 5v amplitude .i m converting that amplitude in 2 different firing pulse for 2 different pair of scr.and am giving these 2 pulse to different...
Hello everyon my project is to control the firing angle of bridge recrifier using 4 SCR .by using PIC Microcontroller .i am ising ZCD and ADC logic and am getting the varying pulse at the output of PIC but how to fire 4 SCR using that plz help me.
