Objectives
This course provides an introduction to power electronics and its applications. The
course starts with coverage of modern power semiconductor devices, their
characteristic, and drive circuit design. Topologies of power electronic circuits
including single phase and three phase ac-dc rectifiers, ac-ac voltage controllers, dcdc converters, and dc-ac inverters will be covered along with their control techniques.
Applications of modern power electronic devices are also included with emphasis on
switch mode and linear regulators. These objectives confirm to the ones’ listed in
HEC guidelines as a, d, e, & f.
Expected
Outcomes
In accordance with HEC curriculum outcomes a, d, & k, students at the end of the course
should be able to:
 Develop and quantify common performance objectives for power electronic
circuits.
 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.
