Modern arc welding machines utilize controllable high frequency DC/DC power supply with high dynamic and steady state current regulation performance. In the design robustness, small size and low weight, low complexity, and high efficiency are the defining criteria. The most suitable approach for a 5 kW arc welding machine power supply application is the high frequency Full-Bridge Phase-Shifted Zero Voltage Switching (FB-PS-ZVS) DC/DC converter with an isolation transformer. This converter not only gives the advantage of zero voltage switching for a wide load current range, it also provides reduced Electromagnetic Interference (EMI) and reduced component stress compared to standard PWM converters. In this thesis a FB-PS-ZVS DC/DC converter with 5 kW power rating is designed for modern arc welding machine applications. IGBTs are utilized at 50 kHz switching frequency for high efficiency and control bandwidth. The output current of the DC/DC converter is controlled via a Digital Signal Processor (DSP) control platform. The performance of the designed DC/DC converter is evaluated via the computer simulations and the experimental study of the constructed prototype.

Design of boost converter for educational test bench
Öztürk, Orhan; Üçtuğ, Yıldırım; Department of Electrical and Electronics Engineering (2006)
In this thesis a boost converter is developed to be used as a test bench in power electronics laboratory. For this purpose, first, steady-state and small-signal analyses of a boost converter are carried out, then closed loop control of the converter is developed and simulated. Then, the circuit is designed and manufactured. The test results are compared with the simulation results. Finally, an experimantal procedure is prepared to enable the students to perform the experiment in the laboratory with the test...
RF coil system design for MRI applications inhomogeneous main magnetic field
Yılmaz, Ayhan Ozan; Aşkar, Murat; Department of Electrical and Electronics Engineering (2007)
In this study, RF coil geometries are designed for MRI applications using inhomogeneous main magnetic fields. The current density distributions that can produce the desired RF magnetic field characteristics are obtained on predefined cubic, cylindrical and planar surfaces and Tikhonov, CGLS, TSVD and Rutisbauer regularization methods are applied to match the desired and generated magnetic fields. The conductor paths, which can produce the current density distribution calculated for each surface selection an...
Optimum current injection strategy for magnetic resonance electrical impedance tomography
Altunel, Haluk; Eyüboğlu, Behçet Murat; Department of Electrical and Electronics Engineering (2008)
In this thesis, optimum current injection strategy for Magnetic Resonance Electrical Impedance Tomography (MREIT) is studied. Distinguishability measure based on magnetic flux density is defined for MREIT. Limit of distinguishability is analytically derived for an infinitely long cylinder with concentric and eccentric inhomogeneities. When distinguishability limits of MREIT and Electrical Impedance Tomography (EIT) are compared, it is found that MREIT is capable of detecting smaller perturbations than EIT. ...
Design, implementation and engineering aspects of tcr for industrial svc systems
Mutluer, Halas Bilge; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2008)
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 pu...
Design of buck converter for educational test bench
Kılıç, Ümit Erdem; Üçtuğ, Yıldırım; Department of Electrical and Electronics Engineering (2006)
In this thesis a buck converter has been developed to be used as a test bench in power electronics laboratory. For this purpose, first, steady-state and small-signal analyses of a buck converter is carried out, then open-loop and closed-loop control of the converter are developed and simulated. Then, the circuit is manufactured and tested. The test results are compared with the simulation results. Finally, an experimantal procedure is prepared to enable the students to perform the experiment in the laborato...
