STAFFING:

PRE-REQUISITE(S)

70326+E2003

RATIONALE:

The  application of semiconductor devices in the electric power  field
has  been steadily increasing, and a study of power electronics is now
a  feature of most electrical engineering courses. An understanding of
the principle of operation of commonly used power electronic equipment
will  be  a  valuable asset for the engineering associate  working  in
almost any field of modern electrical engineering.

SYNOPSIS:

This  unit introduces students to the general principles and  problems
of  power  electronic engineering. At the end of the unit,  a  student
should  be familiar with the devices used in power electronics,  their
characteristics,   ratings  and  limitations;  and  understand   their
application  in a wide range of converters, motor control schemes,  no
break  power  supplies,  and  industrial  process  control,  including
induction heating and melting.

OBJECTIVES:

After completing all the set tasks in this unit a student
should :

1. be able to describe the operation, ratings and characteristics
   of a wide range of power electronic devices;
   
2. be aware of the application of these devices in a wide range
   of systems;
   
3. be able to understand typical power electronic circuits and
   their associated waveforms;
   
4. be aware of problems of reliability, power factor, efficiency,
   interference and harmonic suppression.

OTHER REQUIREMENTS:

1    Because  it is normal practice to release model answers  promptly
     after the due date, the penalty for late submission of assignment
     work will normally be the loss of all marks for the assignment.
2    Students must achieve at least 50% of the maximum possible  marks
     in  the  examination,  and  at least 50%  of  the  total  maximum
     possible marks for a pass in this unit.
3    The   Faculty  of  Engineering  and  Surveying  will  NOT  accept
     submission  of  hand written or typed assignments  by  facsimile,
     email  or computer diskette. Students in remote locations who  do
     not  have regular access to postal services may be given  special
     consideration.
4    A  minimum  standard of communication skills must be demonstrated
     in order for a passing grade to be achieved.
