Following is the image of my circuit, I am working at the moment. This is not my own circuit but I am trying to understand and work on it.
Following is the signal I am getting at B'. I do not understand why I am getting bit of noise in between two half waves. This is same at A' also. When I enlarge the image, I get big hump ( Smaller than AC signal). What could cause this? This is the signal immediately after rectification from diode.
I am getting half output from the my system. I am guessing this might be because of the turning of only one gate. Could there be any reasons why one gate can go faulty. I replaced the TRIACS and TRIAC Driver already, but did not help. The vertical glitch lines on each half waveforms on third image, is that because of firing angle? or will any component cause this? I guess the reason being firing angle because this vertical line moves left and right when I decrease and increase the output. Any help will be highly appreciated.
