1.Discuss the efficiency of the three-phase fully-controlled
converter-fed dc motor drive.
2.Current feedback can be obtained by sensing the ac-side currents
and rectifying them to find the armature current.
What is the advantage of this method of current sensing
over direct sensing of armature current?
謝謝大家!!!
