report(s)
Actions Taken
Results
Analysis
- The department should
get a legal software to be
used by the students
Request submitted
to the department
Software not
acquired
No improvement in the
simulation skills
- Use power point to
explain the behavior of
electronic circuits and to
draw the output-waves.
- All topics are
presented using
power point
according to the
textbook content.
Students are more
able to sketch
waveforms of output
signals delivered by
the converters.
Earn of time and more
topics are covered as
planned in course
specification.
- Maintain the short power
point presentation done
by each group of student
in classroom.
One search topic
was assigned to
each group of three
students. Report
and power
presentation were
done.
Outcome (g) “An
ability to
communicate
effectively” was
achieved by 80%
of students.
This outcome is
achieved and the
performance of students
is above the target. It
appears to have helped
their understanding of
the topic as evinced by
various assessments

- Propose a mini design
project such as “Single
phase uncontrolled Full-
wave rectifier” or “Single
phase AC/AC converter”.
Such work mains improving
the ability to design system.
-One design project
was assigned to
each group of two
to three students.

- In addition to the short design
examples presented for each
converter, I suggest to take one
complete power electronics
design problem and solve it
during the lecture.
- Select a design problem
for one of the 4 converters
(AC/DC or AC/AC or
DC/DC or DC/AC) and
show the different steps to
follow including choice of
electronic devices and
evaluation of their
performances.
