Hello everyone,
I have read the following thread and would like to take it one step further.
https://forum.allaboutcircuits.com/threads/3-phase-controlled-rectifier.65175/
My main question is how to you know when to switch on the SCRs if the three phase input in varying in frequency.
For example if the phase voltage has a frequency of 50 Hz, Each SCR must be fired for 60 degrees, so each SCR must be switched on for about 3.33ms.
How do i find out this value when the frequency is varying every cycle?
Thanks,AK
