Investigation of Turn-on and Turn-off Characteristics of Enhancement-Mode GaN Power Transistors

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.

Analysis and design of a compliant variable stroke mechanism
TANIK, ENGİN; Söylemez, Eres (Elsevier BV, 2010-10-01)
In this paper, analysis and design of an underactuated compliant variable stroke mechanism are presented by employing its pseudo-rigid-body model (PRBM). During the design two cases are considered: prescribed output loading and constant input torque. It is shown that this mechanism is suitable where variable stroke is required corresponding to variable output loading. It is also observed that this mechanism is capable of providing nearly constant force over a wide range of input. The analysis and design app...
Investigation of buckling, post-buckling behaviour of variable stiffness composite plates
Cömert, Utku Kaan; Darendeliler, Haluk; Department of Mechanical Engineering (2022-8-31)
In this thesis, buckling and post-buckling behaviour of variable stiffness (VS) composite plates are investigated. VS plates are designed by using quadratic Bezier curves to define fiber paths and a script is written for this purpose. Manufacturing limitations and defects are included into the simulations. In the analyses, Finite Element Method (FEM) is used to solve linear and nonlinear buckling with Hashin failure criterion. The plates constructed by using fiber paths with linear and nonlinear angle varia...
An empirical relationship based on high-pass filtering to estimate usable period range for nonlinear SDOF response
Kale, Özkan; Akkar, Sinan; Department of Civil Engineering (2009)
High-pass filtering that is one of the most efficient methods in removing long-period noise of accelerograms is investigated for its effect on nonlinear oscillator deformation response. Within this context, uncertainty in filter cut-off periods that would significantly modify the low-frequency content of accelerograms come into prominence for obtaining reliable long-period displacement response. Analog and digital ground-motion records from recently compiled Turkish strong-motion database are used and these...
Characterization of cross-coupling in capacitive micromachined ultrasonic transducers
Bayram, Barış; Yaralioglu, GG; Oralkan, O; Lin, DS; Zhuang, XF; Ergun, AS; Sarioglu, AF; Wong, SH; Khuri-Yakub, BT (2005-01-01)
This paper analyzes element-to-element and cell-to-cell cross-coupling in capacitive micromachined ultrasonic transducers (cMUTs) using an interferometer. In a 1-D linear cMUT array immersed in oil, a single element was excited, and membrane displacements were measured at different positions along the array with an interferometer. Electrical measurements of the received voltage on each array element were also performed simultaneously to verify the optical measurements. The array was then covered with a poly...
