hi, i search three phase controlled rectifier the problem is how i will code the firing angle for the six thyristors using pic microcontroller

 

Do you have a present means of detecting each phase angle in order to fire each SCR? If so how?
Max.

Max.

I don't have how to begin i search the internet about that but I couldn't find any thing if you have any articles or pdf can i understand

 

Hello,

Have a look at the lower part of this page of the EDUCYPEDIA for links on 3 phase rectifiers:

I noticed some links will not work, but you could try to find them beack in the internet archive:

3ph SCR control of DC brushed motors has gone out of style now with the advent of PWM control, it might be worth looking in to this method?
Picmicro's have inbuilt PWM modules for this purpose.

i need to know how to set the six firing angles in the code
