Aging Tracking for SiC MOSFETs - 08/2021 - Now

SiC MOSFETs experience aging-related degradation throughout their lifetime. Developing a health monitoring circuit (HMC) bolsters the system-level reliability. Nevertheless, a HMC must have an ultra-high precision to sense parameter variations in MOSFET. I developed an online impedance characterization circuit which can track device channel resistance and bond-wire inductance. It does not require an additional current sensor and can measure resistance and inductance with mΩ and pH precision. The developed solution has a comparable size with a small gate-driver circuit and can be further optimized for volume. Up to now, I have developed 6 different versions of the proposed HMC as shown below.

Development of a GaN half-bridge with embedded short circuit detector unit - 09/2019 - 09/2020

A half-bridge with paralleled GaN HEMTs was designed to double the current capacity. Gate and power loop inductances were optimized to ensure balanced current sharing among paralleled devices and achieve clean switching operation. An integrated ultra-fast short-circuit detection unit enhances safety. This half-bridge is capable of operating at up to 500V and 50A. It is intentionally designed with an easily mountable connector interface and used as a power electronic building block. The picture below illustrates the design.

Design of a 5.4-kW GaN Based Bi-directional DC/DC Converter - 09/2019 - 09/2020

For my thesis study, I designed a 5.4 kW GaN-based bi-directional DC/DC converter utilizing interleaved and paralleled half-bridges. The two interleaved bridges minimize ripple stress on passive components, while the paralleled half-bridges within each bridge increase current capability.

Design of a 5 Phase GaN Based Motor Driver - 06/2020 - 07/2021

A five-phase motor driver incorporating GaN-based half-bridges was designed for a fault tolerance study of electric machines. The tests were performed on a low-inductance 5-phase motor and the driver demonstrated the capability to operate with a 30A phase current at a 40 kHz switching frequency.

Design of an Integrated Motor Driver for PCB Motor Application - 07/2020 - 08/2021

We designed a compact, three-phase GaN-based motor driver to maximize the performance of PCB motors in a minimal volume and mass. I played a key role in the design of the integrated motor driver, which operates at a 1 MHz switching frequency.

Integrated Modular Motor Drive (IMMD) - 10/2017 – 10/2019

IMMD is a project where an electrical motor and drive system are combined in one package and the aim is to improve power density and fault tolerance.

I designed a three-phase inverter motor driver using GaN transistors and a general control board that incorporates a DSP, communication tools, and a flyback converter for controlling the IMMD modules. The boards underwent several functional tests in the laboratory, and I developed a GaN transistor model in MATLAB/Simulink to verify the IMMD design in a simulation platform. This research was conducted in collaboration with undergraduate students as part of the IMMD project, and I served as a team leader for those students.

Capstone Design Project - 09/2016 - 06/2017

The project lecture is divided into two semesters, where students work in groups to create and execute a solution aimed at solving a problem.

As part of a five-member team, we endeavored to create a robot capable of playing the Connect Three game. I assumed responsibility for designing the mechanical components of the robot, overseeing its power system and hardware setup, managing the sensors, and programming the microcontroller to perform specific tasks. As a result of our efforts, our design was recognized with an Honorable Mention Prize.

CanSat Competition (METUSAT) - 10/2015 - 06/2016

The CanSat competition is a globally recognized event that is coordinated by the American Astronautical Society (AAS) and American Institute of Aeronautics and Astronautics (AIAA). Teams from around the world participate in this contest, where they are tasked with constructing their own space-themed system. In the month of June, the CanSats are launched in Texas, USA.

As part of a multidisciplinary team, we participated in this competition by designing a model satellite consisting of mechanical and electronic subcomponents. Specifically, I was responsible for developing the Flight Software within the electronic subcomponent. Throughout the preparation period, I gained a wealth of experience in programming Arduino and electronic sensors. Additionally, the competition provided an excellent opportunity to learn about effective teamwork.
