Design, implementation and engineering aspects of tcr for industrial svc systems

Mutluer, Halas Bilge
Design and implementation of TCR (Thyristor Controlled Reactor) for industrial SVC (Static VAr Compensator) systems require special design. Both power stage and control system design and implementation are thoroughly investigated in this thesis. Engineering aspects of TCR design are emphasized and supported with case studies. As the first case study; a novel, unified and relocatable SVC for open cast lignite mining in Turkey is designed, implemented and commissioned. The second case study is the first 12 pulse TCR design and implementation for ladle furnace compensation in the world. The SVC simulation results are verified by data acquired in the field. Real time data are also simulated in EMTDC/PSCAD program to verify the control system responses of the commissioned systems.


Design and implementation of a current source converter based active power filter for medium voltage applications
Terciyanlı, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2010)
This research work is devoted to the design, development and implementation of a Current Source Converter (CSC) based Active Power Filter (APF) for Medium Voltage (MV) applications. A new approach has been proposed to the design of the CSC based APF for reducing the converter kVA rating considerably. This design approach is called the Selective Harmonic Amplification Method (SHAM), and is based on the amplification of some selected harmoniccurrent components of the CSC by the input filter, and the CSC contr...
Hybrid connection of RF MEMS and SMT components in an impedance tuner
Unlu, Mehmet; Topalli, Kagan; Atasoy, Halil Ibrahim; Demir, Şimşek; Aydın Çivi, Hatice Özlem; Akın, Tayfun (Elsevier BV, 2010-01-01)
This paper presents a systematic construction of a model for a hybrid connected RF MEMS and SMT components in a reconfigurable impedance tuner. The double stub hybrid impedance tuner which employs a high number of MEMS switches is selected to demonstrate the feasibility of the connections. In the hybrid tuner, MEMS switches are actuated with DC bias signals, where SMT resistors de-couple RF from the DC lines. The hybrid tuner is realized in two steps, where the MEMS impedance tuner is fabricated on a glass ...
Design of an educational purpose multifunctional dc/dc converter board
Bağlan, Fuat Onur; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2008)
In this thesis a multifunctional DC/DC converter board will be developed for utilization as an educational experiment set in the switched-mode power conversion laboratory of power electronic courses. The board has a generic power-pole structure allowing for easy configuration of various power converter topologies and includes buck, boost, buck-boost, flyback, and forward converter topologies. All the converters can be operated in the open-loop control mode with a switching frequency range of 30-100 kHz and ...
Active clamped ZVS forward converter with soft-switched synchronous rectifier for high efficiency, low output voltage applications
Acik, A; Cadirci, I (Institution of Engineering and Technology (IET), 2003-03-01)
The analysis, design, and implementation of an active clamped ZVS forward converter equipped with a soft-switched synchronous rectifier (ACFC-SR), proposed for high-efficiency low output voltage DC-DC converter applications, is presented. The converter efficiency is maximised due to soft switching of the main, active clamp, synchronous rectifier, and freewheeling MOSFET switches. The operating principles of the ACFC-SR are analysed in detail, and the converter performance is compared with that of alternativ...
Development of mems technology based microwave and millimeter-wave components
Çetintepe, Çağrı; Demir, Şimşek; Department of Electrical and Electronics Engineering (2010)
This thesis presents development of microwave lumped elements for a specific surface-micromachining based technology, a self-contained mechanical characterization of fixed-fixed type beams and realization of a shunt, capacitive-contact RF MEMS switch for millimeter-wave applications. Interdigital capacitor, planar spiral inductor and microstrip patch lumped elements developed in this thesis are tailored for a surface-micromachining technology incorporating a single metallization layer, which allows an easy ...
