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?
A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
