1)A separately excited dc motor is fed from a 230V,50Hz source through a 1F half controlled converter.Its field is fed through 1-F semi converter with zero degree firing angle delay. Ra=0.7O and motor constant=0.5V.Sec/rad. For rated load torque of 15N-m at 1000rpm and for continuous ripple freecurrents determine a) firing angle delay of the armature converter b) rms value of thyristor and freewheeling diode current. c) input powerfactor of the armature converter.
