Consider the 3-hp induction motor in Table 6.10-1 . The machine is being fed from a sine-triangle modulated three-phase bridge with v dc = 280 V. If the machine is being operated at a speed of 1710 rpm and the frequency of the fundamental component of the applied voltages is 60 Hz, plot the torque versus duty cycle as the duty-cycle d is varied from 0 to 5.
