Berkeley EECS researchers win Best Showcase Award at the ARPA-E Energy Innovation Summit

by

EECS graduate students Logan Horowitz, Syed Tahmid Mahbub, Jiarui Zou, and Professor Robert Pilawa-Podgurski have received a Best Showcase Award at the 2024 ARPA-E Energy Innovation Summit. In collaboration with a team from the University of Illinois Urbana-Champaign and other academic and industry partners, the Berkeley team developed technology that aims to drastically improve the efficiency of future data centers. Their work focused on the design of a thermal test vehicle (TTV) for assessing cooling solutions.

The ARPA-E Energy Innovation Summit convenes experts from different technical disciplines and professional communities to address America’s energy challenges. The Summit offers a unique, three-day program, highlighting cutting-edge ideas with the most potential for meaningful impact.

Berkeley EECS wins Best Presentation Awards at IEEE APEC

by

EE grad student Logan Horowitz and post-doc Nathan Miles Ellis, advised by Professor Robert Pilawa-Podgurski, have received awards for outstanding technical presentations at the IEEE Applied Power Electronics Conference (APEC)–the flagship conference in power electronics. 

Logan received a Best Presentation award for his work on a 14-level  Flying-Capacitor-Multilevel inverter for electric vehicles, and Nathan for his work on a 48V-to-1V point-of-load (PoL) converter for aerospace telecommunications and computing applications. Both works demonstrated performance greatly exceeding state-of-the-art capabilities in energy conversion.

The APEC Best Presentation Awards are scored using several criteria, including quality of slides, presentation, and how well the presenter responds to questions. The award is considered a significant professional achievement. APEC 2024 hit record attendance this year, which took place in Long Beach, CA.

EECS Grads win IEEE COMPEL Best Paper Award

by

Graduate students Nathan Brooks, Samantha Coday, Maggie Blackwell, Rose Abramson, and post-doc Nathan Ellis have won the IEEE COMPEL Best Paper Award for their paper, “Operation of Flying Capacitor Multilevel Converters At and Above Resonance.” The paper was presented at the 23rd IEEE Workshop on Control and Modeling for Power Electronics (COMPEL), which took place in Tel Aviv, Israel. COMPEL is the premier conference on the latest advances in modeling, simulation, analysis, and control of power electronics devices, circuits and systems. The criteria for the award are based on the quality of the technical results, write-up, and presentation. The paper describes a new method for operating flying capacitor multilevel converters at and above resonance, which has proven to be more efficient and with better performance than existing methods. In addition to the best paper award, the group, advised by Professor Robert Pilawa-Podgurski, organized and presented a tutorial at the IEEE 7th Southern Power Electronics Conference (SPEC) in December 2022.

Yicheng Zhu wins NVIDIA Graduate Fellowship

by

EECS Ph.D. student Yicheng Zhu (advisor: Robert Pilawa-Podgurski) has won an NVIDIA Graduate Fellowship. Zhu, whose research interests include enabling technologies for high-performance electric power conversion, is one of five recipients of the fellowship, which awards up to $50,000 to each recipient in support of research in areas such as accelerated computing, with fellows tackling projects in deep learning, robotics, computer vision, computer graphics, circuits, autonomous vehicles, and programming systems. Awardees are selected from a highly competitive, global applicant pool and will participate in a summer internship with NVIDIA. Spanning 22 years, NVIDIA has awarded $6 million to nearly 200 students to support graduate research. “Our fellowship recipients are among the most talented graduate students in the world,” said NVIDIA Chief Scientist Bill Dally. “They’re working on some of the most important problems in computer science, and we’re delighted to support their research.” Zhu’s research will explore extreme-performance hybrid switched-capacitor voltage regulation modules for ultra-high-power GPUs, which enables highly efficient and ultra-compact vertical power delivery with fast transient response.

EECS graduate students turn e-waste into art

by

EECS graduate students use leftover printed circuit boards (PCBs) to create art. The result is a beautiful Cal EECS bear in Berkeley blue, centered over the letters E-E-C-S in green, all made up of PCBs, on a towering six by seven plywood base held together by very-high-bond (VHB) double-sided tape. Rahul Iyer, an EECS Ph.D. student advised by EE Prof. Pilawa-Podgurski, had the idea over Thanksgiving break to make use of what would otherwise be e-waste. With the help of Rod Bayliss III, Maggie Blackwell, Sahana Krishnan and Nathan Brooks, all Ph.D. students advised by Pilawa, they set out to repurpose the leftover PCBs, first by printing the silhouette of the Cal bear on a mounting board, tracing the outline of the bear, and then using VHB to tape the PCBs onto the mounting board, filling in the outline. “It was a great bonding activity over Thanksgiving break, especially recollecting projects and past memories when we came across some of the boards,” said Rahul. “I’m so glad I had an opportunity to share in this creative endeavor with my peers. Looking forward to another project in a few years when we collect more PCBs!”

Rod Bayliss and Vivek Nair win 2022 Hertz Fellowships

by

EECS graduate students Roderick Bayliss III (advisor: Robert Pilawa-Podgurski) and Vivek Nair (advisor: Dawn Song) have been selected to receive 2022 Hertz Fellowships.  One of the most prestigious awards of its kind, Hertz Fellowships support PhD students whose research show “the greatest potential to tackle society’s most urgent problems.” Bayliss is developing more efficient and power-dense types of power converters—devices that change the current, voltage or frequency of electrical energy—and inductors, which store energy, to help reduce the world’s dependence on fossil fuels. He earned his B.S. and M.Eng. in Electrical Engineering from MIT.  Nair is developing cutting-edge cryptographic techniques to defend digital infrastructure against sophisticated cyberthreats. He was the youngest-ever recipient of a B.A. and Master’s in computer science from the University of Illinois Urbana-Champaign, and is the founder of Multifactor.com.  Their fellowships will fund up to five years of graduate research with “the freedom to pursue innovative ideas wherever they may lead.”  Hertz Fellows also receive lifelong professional support, including mentoring and networking with a powerful community of more than 1,200 researchers.
