The motor driven by a switch-mode dc-dc converter, which has a bus voltage of 200V. The switching frequency fs = 25 kHz. Calculate and plot the waveforms for va(t), ea(t), ia(t), and id(t) under the following conditions:
a) Motoring in forward direction at a speed of 1500 rpm generating 3Nm of torque.
b) Regenerative breaking from conditions in (a) with a current of 10A.
