This thesis investigates axially extracted virtual cathode oscillator, which is one of the HPM sources, in several aspects. First, the cathode ring structure is defined, and effects of that structure are interpreted. Besides, the dependency between current density characteristics in the diode region of the studied vircator and the defined power conversion efficiency is shown. Moreover, the input characteristic of the vircator is examined in terms of the applied inlet voltage and corresponding inlet current. By taking these waveforms into consideration, the input port of the vircator is modeled with an equivalent electric circuit. Then, the variation of the modeled electric circuit component values with respect to the vircator's design parameters is analyzed.

Design Studies of Axial Vircator for High Power Microwave Generation KÜÇÜK, İBRAHİM SEMİH; TİMUR, BÜŞRA; Tanc, Zafer; Demir, Şimşek (2017-09-27) This paper presents design and simulation results of the cylindrical axial virtual cathode oscillator which is frequently used to damage electronic equipment by generating High Power Microwaves (HPM). Simulations are performed in MAGIC Tool Suite which uses FDTD-PIC algorithm to solve particle beam and field interactions. During the design procedure, AK Gap is changed from 5 mm to 12 mm and the scaling law is verified by simulation results. 9 mm AK gap values are selected as the most suitable one when outpu...
An analytical Network for Switched Reluctance Machines with Highly Saturated Regions Yu, Q.; Laudensack, C.; Gerling, D. (2011-09-10) In this paper an analytical network for flux linkage and flux density distribution of a switched reluctance machine (SRM) is developed based on the magnetic equivalent circuit (MEC). Due to the positional dependent reluctance in the air gap, all paths are separately modeled. Instead of using empirical equations, the effective air gap reluctance is analyzed from machine geometry. Due to high local saturation in the teeth, the machine is discretized into adjustable elements. In addition, the slot leakage and ...
An 80x80 Microbolometer Type Thermal Imaging Sensor using the LWIR-Band CMOS Infrared (CIR) Technology Tankut, Firat; Cologlu, Mustafa H.; Askar, Hidir; Ozturk, Hande; Dumanli, Hilal K.; Oruc, Feyza; Tilkioglu, Bilge; Ugur, Beril; Akar, Orhan Sevket; Tepegoz, Murat; Akın, Tayfun (2017-04-13) This paper introduces an 80x80 microbolometer array with a 35 mu m pixel pitch operating in the 8-12 aem wavelength range, where the detector is fabricated with the LWIR-band CMOS infrared technology, shortly named as CIR, which is a novel microbolometer implementation technique developed to reduce the detector cost in order to enable the use of microbolometer type sensors in high volume markets, such as the consumer market and IoT. Unlike the widely used conventional surface micromachined microbolometer ap...
A readout circuit for QWIP infrared detector arrays using current mirroring integration Tepegoz, M; Akın, Tayfun (2003-09-18) This paper reports a current mirroring integration (CMI) CMOS readout circuit for high-resolution Quantum Well Infrared Photodetectors (QWIPs). The circuit uses a feedback structure with current mirrors to provide stable bias voltage across the photodetectors, which can be adjusted between 0 V and 3.5V. The photodetector current is mirrored to an integration capacitor which can be placed outside of the unit pixel, reducing the pixel area and allowing to integrate the current on larger capacitances for large...
An experimental performance test of a derivative-free non-linear state observer designed for sensorless AC drives Akın, B; Orguner, Umut; Ersak, Aydın (2004-06-05) In this paper, a new Kalman Filtering technique, Unscented Kalman Filter (UKF) is utilized both experimentally and theoretically as a state estimation tool in field-oriented control (FOC) of sensorless AC drives. Using the advantages of this recent derivative-free nonlinear estimation tool, rotor speed and dq-axis fluxes of an induction motor are estimated only with the sensed stator currents and voltages information. In a previous study, simulations has shown that, UKF, whose several intrinsic properties s...
