Q.2 The speed of a 220V,3.73 kW, 1000 rpm d.c. motor is controlled by a single phase full converter. The ac supply is 240V, 50Hz. A very large inductance is in series with the armature. Assume the motor & converter to be lossless. The emf constant is 1.9 V sec/rad. For a speed of 1000 rpm & rated motor current, determine[CO3] i) The firing angle of the converter ii) The rms value of the supply of the supply current & thyristor current. iii) The supply power factor.
