Course Objectives		Elektrik enerjisi evlerde ve sanayide küçük güçlerden yüksek güçlere kadar bir çok uygulamada yaygın olarak günlük yaşamımızın her safhasında kullanılmaktadır. Güç elektroniğinin ana amacı elektrik enerjisinin kalitesini ve kullanılabilirliğini arttırmaktır. Enerjinin verimli kullanılması ve yenilenebilir enerji kaynaklarının (rüzgar, güneş, dalga, vb) devreye girmesi ile dünyamızın kısıtlı enerji kaynaklarının korunması mümkün olacaktır. Güç elektroniği bu hedeflere ulaşmamız için gereken elektrik enerjisi dönüşüm teknikleri konularını incelemektedir.
Course Description		Switching circuits and basic concepts of power electronics. Diode, SCR, Triacs, GTO, BJT, MOSFET, IGBT, MCT's operational characteristics. Controlled and uncontrolled one and three phase rectifiers. DC choppers. Inverters, one and three phase inverters, pulse width modulation and voltage regulation. AC choppers. Cycloconverters. Protection and snubber circuits. Parallel and series operation operation of switches.
Course Outcomes		Students will have a basic knowledge of operation principles of major power electronics circuit types such as rectifiers, inverters, DC and AC choppers.
Pre-requisite(s)		There is no pre-requisite(s) for this course, however, your success in this course heavily depends on the good knowledge of the following topics: 1. Steady-state and transient analysis of linear electric circuits containing resistors, inductors, and capacitors. 2. The behavior of RLC circuits involving switches. 3. Solution of differential equations with initial conditions. 4. Phasor analysis of AC circuits, computing RMS and average values, power factor, meaning of leading and lagging power factors. 5. Apparent, real, and reactive powers in single- and three-phase power system. 6. Algebra with complex numbers, transformation from rectangular to polar coordinate and vice-versa. The above subjects will not be covered/explained in the class - this course assumes you have sufficient knowledge of these topics. If you feel that your background on the above material is insufficient, you are advised to take a look at your circuit's and mathematic's notes and/or books.
Required Facilities		Use of circuit simulation programs such as PSPICE, PSIM, ORCAD, Electronic Workbench, etc. may be required for assignments.
