2022–2023 Spring

Long-term Intern at TUBITAK BILGEM BTE / Embedded Systems and VLSI Design Lab (B840)

I have worked here as a long-term digital design intern for almost 3.5 months working on mostly signal processing and communication protocols.

Custom FFT/IFFT IP: In the first part of my project, I took the FFT of the input signal , filtered the FFT, and then computed its inverse using Vivado’s Fast Fourier Transform (FFT) and BRAM intellectual properties (IPs). After that, I tested and packaged the project’s initial component as a custom IP. I have used Verilog HDL while completing this project.

UART/FIFO/VGA: In the second phase of the project, a UART interface operating in the loopback mode was designed and tested on the PL pmod part of the Zedboard. Then I have designed FIFO for buffering and VGA part of the project. To sum up, I intended to use a monitor to display the sine wave output from the first project using VGA. All of the implementations of the projects were done on the ZedBoard.

2022–2023 Summer

Short-term Intern at Aspilsan Enerji A.Ş. / R&D Department

I have worked here as a short-term intern for 30-workdays. I have mostly worked on designing basic circuits of power electronics which are converter circuits (buck/buck-boost/flyback converter) and designed a Battery Management System.

CAPSULE PROJECTS

2022–2023 Fall

Design and Implementation of an SCR Pulse Circuit, Controlled Full Wave Rectifier, Shunt Current, Measurement Circuit, DC/DC Boost Converter, DC Motor Drive: The design and implementation of these circuits are done according to the specifications. (PSIM, LTspice, MATLAB Simulink)

Real-time Audio Signal Processing on Zedboard FPGA: The hardware that the system is implemented on is the Zedboard development board with Zynq®-7000 All Programmable SoC. I have used PL and PS part together. I filtered the audio signal, added some noise, and then removed the noise basically using buttons on the board. (Vivado, VHDL)

Senior Design Project: Energy harvesting with triboelectric nano-generators. After the energy harvesting part, we tried to store it. First, we have rectified the signal and give it to the boost converter so that we can get a more stable voltage and current to charge a battery. We have controlled the converter circuit with STM32 F103C8.

2021–22 Spring

Single Phase Transformer Design: Designing and optimization of a single phase 0.5 KVA 220 / 110 V, 50 Hz transformer with maximum efficiency and minimum cost (ANSYS Electronics Desktop) 4 pole PM Machine Design: Designing and optimization of a 4 pole 100W synchronous PM machine at 1500rpm, 50V peak, 1A peak with maximum efficiency and minimum cost (ANSYS Electronics Desktop)

Find & Grasp an Object by Husky Robot using ROS: Finding and grasping the object on the conveyor belt with sensors mounted on the manipulator while moving the Husky (Visual Studio Code, ROS, Ubuntu, VMware, Gazebo)

Senior Design Project: Triboelectric based Energy Harvesting, PDMS & Kapton materials are used to generate the TENG which converts mechanical energy into electrical energy.

2021–22 Fall

Line Follower Robots: Construction of two line-follower robots and controlling it with PID via STM32F103C8. (Keil, STM32CubeMX)
