3.22 A large magnet load consists of an inductance of 18.5 H and resistance of 50 2 is to be supplied from a 400 V, 50 Hz, three-phase source through a fully controlled full-wave, three-phase rectifier bridge as or shown in Fig.3.68. It is required to determine: (a) The power delivered to the magnet at firing angle of 60°. FO.E.grd ni (b) The maximum d.c. voltage Vdc,max and maximum current Tsonersubde,max which can be supplied from this rectifier, bool adi d of bemua (c) The delay angle a required to give a magnet current of 4A.
