Course

Description

This course provides an introduction to power electronics and its applications.

The
course starts with coverage of modern power semiconductor devices, their
characteristic, and their drive circuit de
sign. Topologies of power electronic circuits
including single phase and three phase ac
-
dc
rectifi
ers
,
ac voltage controllers,
dc
-
dc
conver
ters
, and
d
c
-
ac
inverters
will be

covered along with t
heir control techniques.
Application
s

of modern power electroni
c devices
are also included with emphasis o
n
switch mode and linear
regulators
.


Expected
Outcomes

Upon completion of this course, students will:



Develop

and quantify common performance objectives for power electronic
circuits, such as efficiency, power

factor, etc.



develop simple power electronic converter topologies to meet certain functional
specifications



analyze power electronic converter operation to develop design guidelines for
choice of switching devices and reactive elements
