Basics of Semiconductors:
Most electronics engineers, myself included, often lack a deep understanding of the physics behind electronics and semiconductor components. Acknowledging this gap, I began studying semiconductor fundamentals in 2019. After completing my initial round of research, it became clear there was still much more to grasp. As the saying goes, the best way to learn something deeply is to teach it. So, I decided to create a series of educational videos on semiconductor fundamentals, a project that took two years of planning, research, scripting, recording, editing, and publishing.

PELS P3 Talk
Each year, the IEEE Power Electronics Society (IEEE PELS TC2) hosts a global 3-minute presentation competition for recent PhD graduates in power electronics. My presentation was selected as one of the top five worldwide and received the 2020 IEEE PELS Prize PhD Thesis Talk (P3 Talk) award.
I’m grateful to IEEE PELS and the expert reviewers who dedicated their time to organizing and evaluating the competition. The challenge involved creating a high-quality, 3-minute video clearly presenting the problem, solution, and key outcomes of the research.
In my PhD work, I introduced the theory of the homopolarity cycle for resonant converters and applied it to develop an advanced three-layer control strategy. This innovation enhanced both large- and small-signal closed-loop performance and efficiency. The approach is applicable to a wide range of systems, including electric vehicles, renewable energy conversion, LED drivers, and other DC/DC power conversion applications.
