a) Figure Q2 (a) shows a single-phase, full-converter drive used to control the field
and armature part of the separately excited de motor. The field and armature of the
converter is supplied with single phase, 218 V, 60 Hz ac supply. Assume that the
full-converter which is connected to the field circuit is set to the maximum possible
value. The armature and field resistance of the motor is 0.41 2 and 148 Q
respectively. The motor voltage constant is Kv = 0.7032 V/A rad/s and the load
torque is TL = 65 N.m at 1000 rpm.
) Analyse the performance parameters of the full-converter drive by determining
the value of current supplied to the field circuit and the delay angle of the
converter in the armature circuit to run the motor at 1000 rpm.
) Assume that the thyristor T1 is disconnected from the supply. Analyse the
performance of the converter drive by determining the field current and delay
angle of the armature circuit.
