A linear-generator topology is proposed for wave-energy applications. The main significance of the generator topology is that the relative position of the magnets, copper, and steels has been chosen so that there are no magnetic attraction forces between a stator and a permanent-magnet (PM) translator. The lack of magnetic forces and the modular nature of the generator topology make the manufacture and assembly of the generator easier than a conventional iron-cored PM linear generator. Analytical modeling techniques are described with a genetic-algorithm optimization method. The proposed topology is implemented to an Archimedes-wave-swing wave-energy converter. A 50-kW prototype has been built to prove the concept, and the no-load-and load-test results are presented.

ANALYSIS OF MILLIMETER WAVE-GUIDES ON ANISOTROPIC SUBSTRATES USING THE 3-DIMENSIONAL TRANSMISSION-LINE MATRIX-METHOD BULUTAY, C; PRASAD, S (1993-06-01) Three-dimensional condensed asymmetrical node, variable grid, transmission-line matrix (TLM) method has been used in analyzing several millimeter waveguides on anisotropic substrates. The dispersion characteristics of image guides together with field and energy confinement properties at millimeter-wave frequencies have been investigated. Edge coupled microstrip line on a uniaxial substrate is analyzed for the even and odd mode dispersion characteristics. Finally the same analysis is repeated for bilateral f...
Design and implementation of a voltage source converter based statcom for reactive power compensation and harmonic filtering Çetin, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007) In this thesis, design and implementation of a distribution-type, voltage source converter (VSC) based static synchronous compensator (D-STATCOM) having the simplest converter and coupling transformer topologies have been carried out. The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
Design and simulation of nana-optical beam generators based on zero-index materials Eris, Ozgur; Abanuzoglu, Tutku; Ergül, Özgür Salih (2019-09-01) We present design and computational analysis of near-zero-index (NZI) structures that act as nano-optical beam generators when excited internally by isotropic sources. The designed structures have homogenized shell geometries with various modifications to generate asymmetric tridirectional, bidirectional, and unidirectional beams, in addition to symmetric ones. NZI properties make it possible to generate beams from planar surfaces, while numerical results show that the behavior of a shell is very sensitive ...
Design of advanced motion command generators utilizing FPGA Yaman, Ulaş; Dölen, Melik; Department of Mechanical Engineering (2010) In this study, universal motion command generator systems utilizing a Field Programmable Gate Array (FPGA) and an interface board for Robotics and Computer Numerical Control (CNC) applications have been developed. These command generation systems can be classified into two main groups as polynomial approximation and data compression based methods. In the former type of command generation methods, the command trajectory is firstly divided into segments according to the inflection points. Then, the segments a...
Design of a computer interface for automatic finite element analysis of an excavator boom Yener, Mehmet; Söylemez, Eres; Department of Mechanical Engineering (2005) The aim of this study is to design a computer interface, which links the user to commercial Finite Element Analysis (FEA) program, MSC.Marc-Mentat to make automatic FE analysis of an excavator boom by using DELPHI as platform. Parametrization of boom geometry is done to add some flexibility to interface called OPTIBOOM. Parametric FE analysis of a boom shortens the design stages and helps to find the optimum design in terms of stresses and mass.
