In this thesis an educational test bench for studying the power quality attributes of the commonly used single-phase full-bridge diode rectifiers with power factor correction (PFC) circuits is designed and tested. This thesis covers the active and passive power factor correction methods for single-phase bridge rectifier. Passive filtering approach with dc side inductor and tuned filter along with active filtering approach via singleswitch boost converter is considered. Analysis, simulation, and design of a single phase rectifier and PFC circuits is followed by hardware implementation and tests. In the active PFC approach, various control methods is applied and compared. The educational bench is aimed to useful for undergraduate and graduate power electronics course, power quality related laboratory studies.

Design of a ZVS QRC converter for educational test bench Şengüzel, İsmail; Üçtuğ, Yıldırım; Department of Electrical and Electronics Engineering (2006) In this thesis, the conventional pulse-width modulated (PWM) and zero-voltage switching (ZVS) quasi-resonant buck converters are analyzed and a variable-frequency control technique is proposed to regulate the output voltage due to the immediate input line and load changes. The quasi-resonant technique provides favorable switching conditions for active switch to reduce switching losses and electromagnetic interference (EMI). The method is based on shaping the voltage across the active switch in quasisinusoid...
A new design of excitation mechanism to be exploited by modern rf excited co2 lasers Kurucu, R. Salur; Esendemir, Akif; Department of Physics (2004) On this thesis work, design and construction of an up to date complete RF excitation system was intended. This excitation system is mainly based on highly efficient switching power generators and proper coupling of the power to the object plasma. This new excitation system design should answer the demands of today's progressed CO2 lasers on various power ranges. Though it could be used by a large variety of applications including RF plasma and RF heating, on the first occasion in order to define design cons...
Comparison of Matrix Converter Induction Motor Drive Control Methods Lettl, Jiri; Kuzmanovic, Dragan; Fligl, Stanislav (2011-09-10) In this paper, the implementation of the Field Oriented Control and the Direct Torque Control in matrix converter supplied induction motor drives is analysed, and compared with the implementation in drives supplied by the Voltage Source Inverter. The analysis is accompanied by the results of numerical simulations and experimental implementations of these two control methods.
Design and Implementation of a 154-kV +/- 50-Mvar Transmission STATCOM Based on 21-Level Cascaded Multilevel Converter Gultekin, Burhan; Gercek, Cem Ozgur; Atalik, Tevhid; Deniz, Mustafa; Bicer, Nazan; Ermiş, Muammer; Kose, Kemal Nadir; Ermis, Cezmi; Koc, Erkan; Cadirci, Isik; Acik, Adnan; Akkaya, Yener; Toygar, Hikmet; Bideci, Semih (2012-05-01) In this research work, the design and implementation of a 154-kV +/- 50-Mvar transmission static synchronous compensator (T-STATCOM) have been carried out primarily for the purposes of reactive power compensation and terminal voltage regulation and secondarily for power system stability. The implemented T-STATCOM consists of five 10.5-kV +/- 12-Mvar cascaded multilevel converter (CMC) modules operating in parallel. The power stage of each CMC is composed of five series-connected H-bridges (HBs) in each phas...
Development and characterization of low-cost uncooled infrared sensors for commercial applications Tankut, Firat; Akın, Tayfun; Eminoğlu, Selim; Department of Electrical and Electronics Engineering (2013) This thesis reports the study on the development and characterization of low-cost uncooled microbolometer type infrared detectors, which are fabricated using standard CMOS and MEMS processes. Characterization of the detectors is the first step of developing infrared sensors with better performance. The characterized pixel has a 70 μm pitch and includes 4 serially connected diodes as the detector circuit. Thermal conductance (Gth), temperature sensitivity (TC) and, optical absorption are measured in scope of...
