A three phase dual converter is used to control the speed of a 75kW, 600V, 1800rpm separately excited dc motor. The dual converter is operated from a three phase, 480V, 60Hz supply and is losslessT. he motor parameteras reR u: 0.1O,L u: 5mH, kO:0.3Vlrpm (Eu: k@n).T he rated armature current is 1304.

a) Using circuit diagrams showing current directions in each mode of operation, describe how a dual converter is operated in the motoring and generating modes.
