Only a Double excited Electrical machine can act as a
Generator. Please note eg. you cannot generate power from a
squirel cage induction motor as it does not have a dual
power source, it can only operate as a motor as the rotor
is short ckted. In all other cases where the stator
(winding) and rotors(armature) are powered seperately, only
then energy can be converted from mechanical to electrical
(generator) or electrical to mechanical (Motor)

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?
