Course Outcome
ELK331E FALL 2012
1. The answer of "What is Power Electronics?" question and application areas of power
electronics, classification of power converters. Ideal switch and rectifier. Semiconductor
power switching devices used in power electronic circuits: Diode, bipolar junction
transistor (BJT), silicon controlled rectifier (thyristor), triac, diac, gate turn-off thyristor
(GTO), mosfet, insulated-gate bipolar transistor (IGBT), integrated-gate commutated
thyristor (IGCT), and injection-enhanced gate transistor (IEGT). I-V characteristics,
operation principles, maximum voltage and current ratings.
2. Power Semiconductor switches continued. Gating circuits for controlled semiconductor
switches. Series and parallel commutation circuits for turning-off of thyristors.
3. AC-DC: Alternating Current - Direct Current converters (rectifiers). Single phase half-wave
uncontrolled and controlled rectifiers. Operating principles (voltage and current
waveshapes, analytic solutions, power factor, etc.) for resistive, resistive-inductive and
resistive-inductive-constant voltage load conditions.
4. Single phase full-wave uncontrolled, half-controlled and controlled rectifiers. Operating
principles (voltage and current waveshapes, analytic solutions, power factor, etc.) for
different load conditions.

6. Three-phase half-wave uncontrolled and controlled rectifiers, three-phase full-wave
uncontrolled, half-controlled and controlled rectifiers, 12-pulse rectifiers, power factor.
7. Three-phase rectifiers continued.
8. AC-AC: Alternating Current - Alternating Current Converters (AC choppers). International
standards that limits the maximum values of harmonics injected to the utility at the point
of common coupling: IEEE 519-1992, IEC 555-2. Single- and three-phase AC choppers, phase
control and burst-firing control methods, resistive and resistive-inductive load conditions.
Comparison of phase control and burst-firing control methods in terms of generated
harmonics and application areas. Direct frequency converters: Cycloconverters.
