High Frequency, High-Power Density Power Converters
Zahra Saadatizadeh | zs450@msstate.edu
Abstract: In this research seminar, the methodology for designing high-frequency converters will be presented. As the operating frequency increases, the size of the converter decreases, making it particularly appealing for various power converter applications, including electric vehicles (EVs), space applications, renewable energy systems, and radar systems. These applications cover a wide range of power levels, from low to high. Consequently, regardless of the application and power level requirements, the primary goal is to minimize the size and weight of power converters as much as possible. Increasing the operating frequency enables higher power density in converters for different applications, depending on their power demands. The presentation will cover analysis methods, constraints, and challenges associated with designing high-switching-frequency power converters for ultra-compact implementations in specific applications. However, increasing the switching frequency to enhance power density introduces design constraints. Therefore, achieving efficient converter operation requires an optimal trade-off among size, weight, power, and cost (SWaP-C) concerning the operating frequency.

Dr. Zahra Saadatizadeh (Member, IEEE) received her Ph.D. degree in 2020 from the Faculty of Electrical and Computer Engineering at the University of Tabriz, Tabriz, Iran. She was a Ph.D. Visiting Scholar with the Aalborg University, Aalborg, Denmark from 2019 to 2020. She was a Postdoctoral Fellow in the Department of Electrical Engineering at the University of Arkansas, Fayetteville, AR, USA from 2021 to 2024. She was the recipient of the IEEE TPEL journal outstanding reviewer award in 2023. She was a winner of the WIE (Women in Engineering) grant and served as a technical session chair at ECCE 2022 in Detroit, Michigan. Her major fields of interest encompass the analysis, modeling, design, control, and implementation of power electronic converters/inverters. This includes coupled-inductor/switched-capacitor-based converters, high step-up/high step-down converters, multiport converters, and high switching frequency (MHz-range) isolated/non-isolated converters applicable for photovoltaic (PV) systems, electric vehicle (EV), etc. Additionally, her research includes optimization design methods for power converters..
