This course deals with application of power semiconductor devices to the efficient conversion of electrical energy. Specific topics include circuit analysis, signal analysis and energy concepts in the power electronics systems; semiconductor switching devices (IGBTs, Thyristors, Diods etc.); topologies and design of switching power converters (AC-DC, DC-DC and DC-AC); control of switching power converters; application examples and case study.


To provide students with the fundamental concepts of power electronics and to equip them for advanced study and research in the area. An introduction to the use of repetitively-switched electronic circuits for the conversion and regulation of electrical power. The basic converters and their steady-state analysis. Dynamic modeling analysis using the state-space averaging method. Fundamentals of inductor, transformer, and semiconductor switch design.


  • describe fundamental concepts of power electronics; recognize operation and analyze the basic switching power converters (dc-to-dc, ac-to-dc, dc-to-ac) with and without isolation
  • use analysis methods as applied to the repetitively-switched electronic circuits for the conversion and regulation of electrical power flow
  • select power switching elements (transistors and diodes) and design basic dc-to-dc converters to satisfy given specification
  • understand operation and design basic magnetic structures (inductance and transformer)
  • apply mathematical modeling techniques and averaging of the switching circuits behavior
  • design control algorithms for switching power converters
