Investigation of Turn-on and Turn-off Characteristics of Enhancement-Mode GaN Power Transistors
Karakaya, Furkan; Dilberoğlu, Mecid Uğur; Keysan, Ozan (2018-10-30)
In this paper, turn-on and turn-off switching behavior of 650V enhancement-mode GaN power FETs are investigated. An analytical model is developed to analyze the current-voltage characteristics of the device during switching transients both with and without the effects of parasitic components. In addition, the effect of the temperature and circuit parameters on the switching characteristics are investigated.
Investigation of geometrical factors for determining fracture toughness with the modified ring test
Alpay, Ceyda; Tutluoğlu, Levent; Department of Mining Engineering (2008)
Modified Ring specimens are of the shape of discs having a hole inside and flattened ends. These specimens are used for determination of Mode I fracture toughness. Finite element program, named ABAQUS, is used for numerical modeling for finding stress intensity factors. Varying disc geometries were used for the experiments and numerical modeling in which size of the flat ends, radius of the hole inside, and external radius of the specimen were varied. Experiments were done by using pink Ankara andesite. Eff...
Investigation of variable bead widths in FFF process
Gharehpapagh, Bahar; Dölen, Melik; Yaman, Ulaş (2019-01-01)
Fused filament fabrication technology provides the opportunity to produce complex objects with sophisticated interior features. Here, extruding variable bead widths for desktop 3D printers is presented in order to improve resolution and to decrease the build time. In the proposed method, the cross-section is continuously varied according to the geometric features associated with the layers. That is, thinner beads can be utilized to print features with higher accuracy such as the outer surfaces, edges/corner...
Investigation of parallel-connected GaN E-HEMT VSI-based servo drives
Yürük, Hüseyin; Keysan, Ozan; Department of Electrical and Electronics Engineering (2022-1-19)
Nonlinearities in voltage source inverters (VSIs) are thought to be the primary cause of output voltage distortions which cause low-order harmonics in the output current. These nonlinearities also considerably degrades control performance and system stability for low-speed applications with low-inductance motors, particularly when the system operates in the low-torque area. The impact of the nonlinearities on the phase current and current control of a silicon (Si) metal-oxide-semiconductor field-effect tran...
Investigation of the particle breakage parameters in locked-cycle ball milling
Acar, Cemil; Hoşten, Çetin; Department of Mining Engineering (2012)
Size reduction processes, particularly fine grinding systems, in mineral processing and cement production plants constitute a great portion of energy consumption and operating costs. Therefore, the grinding systems should be designed properly and operated under optimum conditions to achieve productive and cost effective operations. The use of simulation based on kinetic mathematical models of grinding has proven useful in this respect. The kinetic models contain two essential parameters, namely, breakage ra...
