AIM

To study and understand the operation of electric drives controlled from a power

electronic converter and to introduce the design concepts of controllers.

OBJECTIVES

 To understand the stable steady-state operation and transient dynamics of a motorload

system.

 To study and analyze the operation of the converter / chopper fed dc drive and to

solve simple problems.

 To study and understand the operation of both classical and modern induction motor

drives.

 To understand the differences between synchronous motor drive and induction motor

drive and to learn the basics of permanent magnet synchronous motor drives.

 To analyze and design the current and speed controllers for a closed loop solid-state

DC motor drive and simulation using a software package
