I received my Ph.D. and MS degrees in Electrical Engineering. I have conducted research on the design and implementation of power units for electric vehicle power systems and smart-grid technologies during my academic life. My efforts resulted in 18 journal publications, 24 conference proceedings, and 12 projects. Furthermore, I have supervised 1 Ph.D. and 3 MSc students. Most of the projects, I have supervised and participated, in are related to electric vehicles and smart-grid technologies. Also, the projects are mostly experimental-based research. Thus, I have performed hands-on experiences such as electronic circuit and PCB design (especially for power electronic applications), building experimental setups, and programming microcontrollers for industrial and power electronic devices. Some of the research projects that I have been involved in; - Design and implement a dc-dc power converter for energy management in fuel-cell/ultracapacitor hybrid power train in electric vehicles, funded by Yildiz Technical University, PI (Applicant), Aug. 2014 – Dec. 2016. - Design and implementation of a double input and bi-directional dc-dc power converter for energy management in battery/ultracapacitor hybrid power train in electric vehicles, funded by The Scientific and Technological Research Council of Turkey, PI (Applicant), Sep. 2013- March 2016. - Design a smart plug for energy management in smart-grid, Collaborated with VİKO by Panasonic, funded by Republic of Turkey Ministry of Science Industry and Technology (SANTEZ), Researcher (Co-PI) Oct. 2013 – Sep. 2014. Since 2017 I have designed and prototyped many projects for industrial applications. Some of them; - Generic thermostat for thermocouple-based application ( with fuzzy-logic control) - Peristaltic Pump Control Unit (0.01 mL resolution) - Timer; included 3 independent time options for exposition machines. - Controller for textile ironing machine (including hot steam boiler control) - Liquid Level Control Relay (3 models) - PAD Print Machine Control Unit - AC phase control relay - Safety Relay for two-hand control systems - Control unit for hot-transfer-print machines (with fuzzy-logic heat control) - Infrared Textile Dryer control unit (control card and power-electronics layer) - RF remote control unit (with learning protocol) - 3-phase synchronization sensor for high-speed rotating system (specifically for a raising machine) - Humidity sensor for industrial textile dryer machines. Furthermore, I have designed some custom things for custom test and research projects; - Python app for monitoring data from PLC (via MODBUS TCPIP) on an HDMI display. - Arduino UNO-based custom board for teaching coding to kids. Also, I have done mBlock libraries for that board. - Some applications with RP Pico and micropython for tests. - Voltage event recorder with ESP8266 also has IoT feature ([login to view URL]) - Electrical Energy Meter with ESP32 and SIM800L has an IoT feature (Google Firebase)

Fuel cell and ultra-capacitor hybridization: A prototype test bench based analysis for EVs
International Journal of Hydrogen Energy
A test bench of such an FC/UC hybrid configuration that can emulate the dynamics of vehicular systems is presented in this paper. Experimental results with small-scale devices, a PEMFC (5 kW, 48 V) manufactured by Plug Power® Company, and a UC bank composed of 430 F, 16 V and 165 F, 48 V UC modules manufactured by Maxwell Technologies® Company, illustrate the successful performance analysis of employed energy management schemes during similar drive cycles.
Fuel consumption comparison of different BAT/UC hybridization topologies for FCV on a test bench
IEEE Journal of Emerging and Selected Topics in Power Electronics
One of the main issues significantly affecting the FCV performance is the chosen hybrid system topology along with system components, which requires research to find the best hybrid structure for the lowest fuel consumption. In this regard, this paper demonstrates a detailed comparison of four different hybrid FC power-train configurations with feasible battery and ultracapacitor (UC) combinations, on a test bench.
A power quality monitoring system based on MATLAB server pages
Turkish Journal of Electrical Engineering & Computer Sciences
In this study, a remote power quality monitoring system for low voltage sub-networks is developed using MATLAB Server Pages (MSP). MATLAB Server Pages, which is an open source technical web programming language, combines MATLAB with integrated J2EE specifications. The proposed PQ monitoring system uses the MATLAB HTML tag library and the data captured by the DAQ hardware to evaluate the Power Quality parameters. The proposed system can be modified as technology and evaluation methods improve.
