Non-invasive real-time diagnosis of PMSM faults implemented in motor control software for mission critical applications Demirel, Aykut; Keysan, Ozan; El-Dalahmeh, Ma'd; Al-Greer, Maher (2024-06-15) The machine's health should be continuously monitored, or a test should be applied on a regular basis to predict failure before fatal damage is incurred. Unexpected failures, particularly in mission-critical applications, ...
Optimal sizing of battery energy storage system for a large-scale offshore wind power plant considering grid code constraints: A Turkish case study Mokhtare, Mohammad Hossein; Keysan, Ozan (2024-01-01) Integration of large-scale wind farms (WFs) into the grid has to meet the critical constraints set in the national grid code. Wind farm operators (WFOs) are inclined to comply with these constraints and avoid heavy penalty...
A Hierarchical Control of Supercapacitor and Microsources in Islanded DC Microgrids Barati, Farhad; Ahmadi, Behzad; Keysan, Ozan (2023-1-01) This paper proposes a hierarchical control approach for SuperCapacitor (SC) energy storage and microsources in islanded DC microgrids. It takes into account microsources' dynamic and steady-state limitations. The proposed ...
Variable Carrier Phase Shift Method for Integrated Contactless Field Excitation System of Electrically Excited Synchronous Motors Ayaz, Enes; Altun, Ogün; Keysan, Ozan (2023-01-01) This paper presents a novel contactless field excitation (CFE) system based on wireless power transfer (WPT), which utilizes the existing voltage source inverter (VSI) of the motor drive for electrical...
Scaling Laws for Electromagnetic Launchers Considering an Existing Pulse Power Supply Gülletutan, Görkem; Keysan, Ozan; Tosun, Nail; Yurdakonar, Ferhat; Yildirim, Baran; Çöklü, Zeynep; Karagöz, Mustafa (2023-01-01) In all areas of engineering, testing full-scale models can be both costly and risky and often not necessary. The scaling laws can be implemented in electromagnetic launchers (EMLs). The objective is to obtain similar tempe...
Ripple Minimization in Asymmetric Interleaved DC-DC Converters Using Neural Networks Alemdar, Ozturk Sahin; Oner, Mustafa Umit; Altun, Ogün; Keysan, Ozan (2023-01-01) Interleaving can be employed to reduce ripples in multiphase DC-DC converters although phases are operated under asymmetric conditions such as different input voltages or loads. To allow ripple minimization under asymmetri...
Design of an optimized PCB motor with a GaN switched integrated motor drive TOKGÖZ, FURKAN; Gülsuna, Özgür; KARAKAYA, FURKAN; ÇAKAL, GÖKHAN; Keysan, Ozan (2022-08-29)
Active fault detection using time and frequency diagnostic features for electrical machine El-Dalahmeh, M.; Al-Greer, Maheer; Demirel, Aykut; Keysan, Ozan (2022-08-29)
Muzzle Voltage Experiments of the EMFY-3 Launcher Tosun, Nail; Karagoz, Mustafa; Yurdakonar, Ferhat; Gulletutan, Gorkem; Yildirim, Baran; Keysan, Ozan (2022-07-01) Muzzle voltage is an essential diagnostic tool used in both contact resistance modeling and transition determination. However, it is challenging to stem the necessary meanings from the collected measurements. In this study...
Generalized Model of Modular Two Element Compensated IPT Systems with Common DC-Bus Ayaz, Enes; Altun, Ogün; Polat, Hakan; Keysan, Ozan (2022-01-01) In this paper, modular IPT systems which have receiver series/parallel compensation with series/parallel common DC-Bus are investigated. For these systems, power sharing between the receiver modules is vulnerable to system...
