This paper reports utilization of high-fill factor absorber structures integrated onto SOI diode type low-cost uncooled microbolometers for broadband absorption performance. Mechanical and optical simulations are performed to assess the enhancement and mechanical stability of the absorber structures. Reported first time in the literature, four types of different absorber structures are employed on the same detector focal plane array (FPA) in order to evaluate the improvement provided by different absorber structures comparatively on the same sensor. This study is conducted on 50 mu m pitched pixels with the FPA format of 160 x 120.

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...

Bay, Olcay; Ermiş, Muammer; Bilgin, Hazım Faruk; Department of Electrical and Electronics Engineering (2017)
In this thesis, analysis, design and implementation of a three-phase 400V, 20 kVA Current Source Inverter (CSI) have been carried out for grid-connected photovoltaic applications based on the multi-string inverter concept. This inverter can be used in large scale photovoltaic (PV) applications by connecting many in parallel at 400V and coupling to medium voltage through a common transformer. The power stage of the inverter is based on the basic full-bridge CSC topology and each power semiconductor which mus...
Design and implementation of a voltage source converter based hybrid active power filter
Uçak, Onur; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2009)
This research work is devoted to the analysis, design and implementation of a shunt connected Hybrid Active Power Filter by the use of a lower rated voltage source PWM converter, and a series connected LC passive filter. In recent years, voltage and current harmonics have become a serious problem both in transmission and distribution systems, due to the widespread usage of non-linear loads such as diode/thyristor rectifiers, electric arc furnaces and motor drives. In order to obtain a better performance tha...
Design and optimization of nano-optical couplers for controlling transmission between electrically isolated nanowires
Karaova, Gokhan; Tahan, Utku; Atmaz, Tuna; Ergül, Özgür Salih (2019-09-01)
© 2019 IEEE.We present design, optimization, and simulation of effective nano-optical couplers to control power transmission in nanowire networks. The couplers consist of careful arrangements of nanoparticles that are designed in an optimization environment based on genetic algorithms and a full-wave solver. The nanowire segments are electrically isolated from each other, leading to more reconfigurable and adaptable systems. We show that, even in the absence of direct contacts between nanowires, high-perfor...
Development of a parylene bonding based fabrication method for MEMS gravimetric resonant based mass sensors
Gökçe, Furkan; Külah, Haluk; Department of Electrical and Electronics Engineering (2017)
This thesis reports development of a parylene bonding based fabrication method for MEMS gravimetric resonant based mass sensors that are integrated with microfluidics for real-time detection when there is a liquid flow through the microfluidic channels. Parylene bonding has been optimized by conducting several bare bonding experiments. The optimized bonding takes place at 250ºC, in vacuum (1 mTorr) and with 2000 N of vertical piston force for 1 hour. The average shear bonding strength is 15.58 MPa for the o...
