1:30 PM: Surgical Energy: Connecting Power Electronics to Patients – Literally!
Daniel Friedrichs
Senior Principal Engineer
Minnetronix Medical
Abstract: Medical applications of power electronics may seem limited to AC/DC and housekeeping power supplies, but an entire class of medical devices exist where power converter outputs are directly connected to patients to achieve different therapeutic effects and improve lives. These include thermally-based therapies (such as ablation and electrosurgery) and electric field-based therapies (such as pulsed field ablation and electro-chemotherapy). Dr. Friedrichs will share examples of clinical therapies dependent on power conversion that include correcting heart arrythmias, ablating tumors, delivering vaccines, and treating genetic disorders. Additionally, this plenary will discuss the unique power electronics challenges that exist in this space, along with future opportunities for power electronics suppliers and designers to accelerate their impact on healthcare.
Daniel Friedrichs leads development of surgical energy systems for Minnetronix Medical, a development and manufacturing partner to the medical device industry. He has specialized in medical power electronics for 15 years and holds over 35 patents related to medical applications of power converters. Dr. Friedrichs has a Ph.D. in Electrical Engineering from the University of Colorado Boulder, is a licensed Professional Engineer, and is a Senior Member of IEEE.
2:00 PM: Opportunities, Progress and Challenges in High-Frequency Power Conversion
David Perreault
Ford Professor of Engineering
Massachusetts Institute of Technology
Abstract: Advances in the performance of power electronics – including their size, efficiency and control bandwidth – are essential to reducing energy consumption and increasing functionality in myriad applications. Increases in switching frequency into the high-frequency (HF, 3-30 MHz) range and beyond offers the potential to reduce energy storage requirements, achieve higher bandwidth and greater miniaturization, and advance applications. At the same time, there are numerous challenges to design at HF, including in devices and passive components, circuits, controls and packaging. This talk will explore opportunities, challenges and progress in the design of HF power electronics. Examples will be provided illustrating high-performance HF power components and systems and their application.

2:30 PM: Innovating for Sustainability and Profitability:
How innovations in efficiency enable us to do good for the environment while doing well as a business
Balu Balakrishnan
Chairman and CEO
Power Integrations
Abstract: Fundamental microelectronics innovations such as high voltage GaN and developments in power converter topology and implementation, are key weapons in the world’s push for decarbonization and energy sustainability. Together, they deliver excellent efficiency, eliminate many parts from system bills of materials, minimize power sub-system volume, heatsinking requirements and enclosure size and weight. The environmental benefits of smaller physical size, reduced complexity and minimal heat dissipation ripple through the supply and use chain from primary mineral sourcing to shipping costs to end user electricity bills. Even so, when sustainability is considered at a business level, there’s often a question of whether or not you can run a growth-oriented and profitable enterprise while providing products with an environmental focus. This presentation discusses the critical role of efficiency in sustainability and how our innovations allow us to do good for the environment while doing well as a business.
Balu Balakrishnan joined Power Integrations in 1989, serving in a variety of roles before becoming president and COO in April 2001. He was named CEO and appointed to the company's board of directors in January 2002. He was named chairman of the board in 2023. Mr. Balakrishnan has more than 40 years of engineering, marketing and management experience in the semiconductor industry, including product-line management responsibility at National Semiconductor Corporation. He is the chief inventor of several key Power Integrations products and technologies and holds more than 200 U.S. patents.

4:00 PM: Fusion Energy is Coming: The Key Role of Power Electronics to Commercial Fusion
AJ Kantor
Chief of Staff
Zap Energy
Matthew C. Thompson
Vice President of Systems Engineering
Zap Energy
Abstract: Fusion energy offers the potential for abundant, on-demand, carbon-free power. But for the past seven decades, fusion has largely been a scientific R&D effort restricted to national labs and universities. In recent years, however, things have begun to shift as private investors have begun backing an array of companies with plans for commercializing fusion — to the tune of $6 billion to date. Zap Energy is one such team, developing an approach to fusion called the sheared-flow-stabilized Z pinch. Zap’s technology avoids the enormous, costly, and complex magnets and lasers of other fusion concepts, but does require several first-of-a-kind systems – including 1MA scale, high-average-power repetitive pulsed power units based on durable solid-state switches. In this keynote Zap’s VP of Systems Engineering Matthew C. Thompson and Chief of Staff AJ Kantor will describe the electrical power handling requirements of fusion systems in general, the fusion industry landscape, what makes Zap’s approach unique, and why power electronics are a critical technology for it to succeed.
AJ Kantor has devoted her career to building bold and challenging technical projects — at Tesla, supporting critical raw material supply chain strategy, internal systems development, a downstream supply chain program, global battery line builds, and the Tesla battery cell program. From there she moved to venture capital, where she focused on hard tech investing and participated on the boards of companies from incubation-stage through IPO. Her experience in large scale, time-bound R&D and technical programs along with her deep exposure to company building at all stages has brought her to Zap Energy, where she is working to bring the same degree of rigor and innovation to the field of fusion power.
C. Thompson leads a 45-person division at Zap Energy tasked with developing fusion power plant technologies including repetitive pulsed power, liquid metal walls, and durable electrodes. Dr. Thompson received his BS in physics from Stanford Univ., and his MS and PhD in experimental plasma physics are from UCLA. He has worked at Lawrence Livermore National Laboratory, TAE Technologies, and BAE Systems. Dr. Thompson is a Fellow of the American Physical Society (APS), past Chair of the APS Forum on Industrial and Applied Physics, and a past Chair of the APS Committee on Careers and Professional Development. He has mentored numerous students, co-founded a major mentoring program called IMPact, and writes about career issues for physical scientists, including in a published book on the subject.
4:30 PM: The Future of AI Requires Efficient Power Delivery inside the Processor
Francesco Carobolante
Director Corporate Strategy
& Ventures
Intel Corporation
Abstract: The development of IVRs (Integrated Voltage Regulators) has been an effort now lasting for over 20 years, but never before it has become such an important focus as it is today. AI processors are approaching currents of 1,000 A and heterogeneous integration is bringing a variety of demanding loads, from traditional logic and memory to optical interfaces, inside the package. As already recognized by many thought leaders, energy efficiency is the ultimate metric to achieve the vision of sustainable advanced computing, which will support the next societal and economic transformation. Co-development of all sub-systems to minimize “Joules/Flop” is the new Moore’s Law to enter the Petaflop era, and power management is one of the most critical enablers to achieve the objective.
Francesco Carobolante explores solutions to advance technology leadership and competitiveness as a Director of Corporate Strategy & Ventures at Intel,. In his previous positions as VP Engineering at Qualcomm and Sr Director at Fairchild and STMicroelectronics, he developed many industry "firsts" in power management, WPT, signal processing, RF, digital audio and many others. Carobolante holds MSEE degrees from University of Padova and UCLA and has authored over 90 issued patents; he is Sr. Member of IEEE, co-chair of IEEE Future Networks Energy Efficiency Working Group, Member of IEEE Heterogeneous Integration Roadmap, and Member of the Steering and Technical Committees for several IEEE PELS and PSMA initiatives, including PwrSoC and EnerHarv.
