COURSE DESCRIPTION
:

This is the third class in a three
-
quarter sequence of evening classes offered by the Industrial Power and Control
Technology program. This course is devoted to the study of electric drives. Th
e fundamentals of power
electronics and electric drives are covered followed by the study of electronic control of direct current and
alternating current motors. Advanced PLC (Programmable Logic Controller) programming is also discussed
and practical appl
ications of using a PLC to control an electric drive are investigated in the lab.


COURSE OBJECTIVES
:


I.

To provide the student with a basic understanding of power electronic devices and circuits.


II.

To familiarize the student with the practical aspect
s of electric drives for both ac and dc motors.

III.

To teach the student how to do advanced programming on the
Allen
-
Bradley SLC
-
500

line of PLCs


and use a PLC to control an electric drive.


IV. To show the student the procedure for sizing motor branch
conductors, motor branch circuit protection,


motor overload protection, and motor disconnects based on Article 430 of the National Electrical Code.


V. Upon completion of EEL 203, students will be able to:


a. State the important safety rules related
to working around electrical devices and specifically those


which relate to working with power electronics and electric drives.


b. Describe the operation of a diode.


c. State the principal characteristics of a diode.


d. Describe a single
-
phase bridg
e rectifier; a three
-
phase, three
-
pulse rectifier; and a three
-
phase, six
-

pulse rectifier.


e. Describe the operation of a thyristor and state the principles of gate firing.


f. Using lab equipment, test a silicon
-
controlled rectifier to determine if th
e device is defective.


g. Using lab equipment, measure the gate trigger voltage and the holding current of a typical SCR.


h. Demonstrate the use of an SCR in controlling the half
-
wave phase and the full
-
wave phase of


an ac power control circuit.


i.

Describe the basic operating characteristics of a UniJunction Transistor (UJT) and demonstrate


UJT half
-

wave and full
-
wave phase control using a typical SCR
-
UJT power control circuit.


j. Describe the operation of a Triac and demonstrate ac power cont
rol using typical Triac control


circuits.


k. Troubleshoot thyristor circuits using basic troubleshooting control circuits.


l. State the differences between a naturally commutated SCR circuit and a forced commutated


SCR circuit.

m. Describe the ope
ration of the following seven basic thyristor circuits:


1)

Controlled rectifier supplying a passive load.


2)

Controlled rectifier supplying an active load.


3)

Naturally commutated inverter.


4)

AC electronic contactor.


5)

Cycloconverter.


6)

Self
-
commu
tated inverter.


7)

DC Chopper


n. State the basic principle of operation of a three
-
phase, six
-
pulse converter.


o. Describe one, two and four
-
quadrant speed control of a dc shunt motor.


p. List several types of electronic ac drives and describe how t
hey operate.


q. Connect

it to control the speed of a



motor.
