Tahmid Mahbub Wins Second Place in the Student Demo Competition at APEC 2026

May 15, 2026 by Dennis Woo

Third-year graduate student Tahmid Mahbub was recently recognized in the student demo competition at APEC 2026 in San Antonio, Texas, winning 2nd place overall. His work, titled “A Novel Multi-Kilowatt Thermal Test Vehicle Utilizing Off-the-Shelf Power Transistors,” demonstrates the generation of localized hot spot patterns for the testing of cooling systems, particularly those destined for data center power delivery systems. His related work from the 2025 ECTC conference can be read at the following link.

Congratulations, Tahmid, on this achievement!

Rod Bayliss III, Emmi Wyttenbach, and Tahmid Mahbub Win Best Presentation Award at APEC 2026

May 15, 2026 by Dennis Woo

Graduate students Rod Bayliss III, Emmi Wyttenbach, and Tahmid Mahbub were recently recognized with best presentation awards for their work at APEC 2026 at San Antonio, Texas! Their work spans three compelling application spaces of switched capacitor converters. Rod was awarded for his work titled “Design and Implementation of a Three-Phase Eight-Level Flying Capacitor Multilevel Rectifier for Future Data Center Power Delivery,” in which he demonstrates the rectification of a 480V grid to a high voltage, 800V DC bus. This research helps to pave the way for high voltage power delivery in data center applications, and can be read at the following link. Emmi’s work also has important implications for the future of data center power delivery. She was awarded for her work titled “An Output Voltage Maximizer for Efficiency Improvement in Resonant Switched-Capacitor Converters,” in which she presents a control technique to improve the efficiency of resonant switched-capacitor converters, a popular choice for intermediate bus converters. Finally, Tahmid was awarded for his work on the design of an exceptionally gravitationally dense power converter for more-electric aircraft DC bus generation. His work is titled “An 8-level Flying Capacitor Multilevel Boost Converter for High-Voltage Power Distribution in Electric Aircraft” and helps pave a path forward for realizable electric flight in the future.

Congratulations to Tahmid, Emmi, and Rod on their incredible achievements!

Nagesh Patle
Syed Tahmid Mahub

BPEC researchers Syed Tahmid Mahbub and Nagesh Patle are recipients of the 2025 Graduate Research Grants from the nonprofit organization Hearts to Humanity Eternal (H2H8). This broadly defined award is granted to thirty graduate researchers each year to fund research that improves world-affecting problems like climate change or furthers advancements in medicine, space exploration, artificial intelligence, and more. Nagesh’s graduate research centers upon ultra-efficient, ultra-dense hybrid switched-capacitor power converters for data center and automotive systems to ease the power delivery limits that constrain modern AI and advanced computing. Tahmid’s graduate research addresses practical challenges in power electronics to help accelerate the adoption of renewable energy and electric transportation, and to reduce power consumption in data centers.
