Hello,
I am working on the three phase full wave rectifier using SCR in delta configuration . I controlling the firing of the SCR using the micro controller and zero crossing detector. But the problem is that controlling angle is going up to 34 only and the output waveform up to 34 degree is O.K. But above
34 it get distorted and rectifier not work properly. I am testing it with a resistance load (electrical bulb).
I testing on the 440 V three phase. I also test semi converter (three SCR and three diode) and it work good.
Thank you
