Exercise#1 • The chopper controls a dc machine with an armature inductance La = 0.2 mH. The armature resistance can be neglected. And the internal motor induced voltage equals to 200v The armature current is 5 A. fs = 30 kHz. D = 0.8 Find the ripple in the armature current. (a) Calculate the maximum and the minimum value of the armature current (b) Sketch the armature current, i(t), and the dc current, i(t).
