I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
