Plenary Sessions

In 2021 he joined Nvidia, where he was appointed Principal Engineer in 2023, and since 2025 he has held the position of Senior Manager of Hardware Engineering. He leads a team of more than 15 engineers working on different solutions to improve power supply for Nvidia GPUs and CPUs, focusing on the design of integrated linear and switching regulators, and noise modeling and simulation.

Miguel has published more than 30 papers in international journals and conferences, and holds around 15 US patents.

This talk focuses on exploring the different challenges and opportunities that arise in the power supply of Nvidia graphics processing units (GPUs), which are widely used in data centers for training and inference in artificial intelligence (AI) applications.

In the first part of the talk, the architecture of GPU power systems will be addressed, from the grid to the chip, introducing some of the fundamental problems that arise at all levels. We will focus on how the combination of GPU structure and AI algorithms tends to generate large voltage fluctuations, as well as the difficulties of providing voltages below 1V and currents of thousands of amperes to next-generation chips.

In the second part, different ways to address these problems will be discussed: for example, what can be done to reduce noise or mitigate its effects, how to design power supplies to meet the conditions mentioned above, and other medium- and long-term solutions.

This roundtable will address the challenges and opportunities of entrepreneurship in the fields of automation, industrial electronics, and instrumentation. Researchers with extensive experience in creating spin-offs and technology-based companies, as well as institutional representatives promoting innovation from public administration, will participate.

Real experiences of knowledge transfer to the market will be shared, along with lessons learned and recommendations for researchers who wish to become entrepreneurs.

In 2015, he was appointed Head of the Power Management and Distribution Section at ESA, where he coordinated technology roadmaps for power conversion and led development programs for satellite power systems.

In 2025, he became Head of the Power Systems, Electromagnetic Compatibility and Space Environment Division, overseeing R&D activities in solar generators, energy storage, electromagnetic compatibility, and space environment effects.

His research interests include high-efficiency switching power supplies, DC/DC converters, converter modeling, and advanced space power systems. He is the author of more than 100 publications in the field.

The talk focuses on the Artemis program power system and the lessons learned from lunar missions carried out in 2023 and 2026.

The development of power systems for crewed spacecraft is a complex task, where development time and variability of flight configurations significantly affect the energy balance. The high redundancy required to ensure reliability also introduces major design challenges.

In this context, simple, scalable, and flexible systems are the best option. Telemetry and control capabilities play a key role, with data availability and frequency being critical aspects for future missions.

Finally, the concept of system-level redundancy is addressed as a more viable alternative to traditional double-fault tolerance, highlighting architectures with multiple interconnectable buses for high-reliability missions.

Carlo Trigona (University of Catania, DIEEI) is a researcher in instrumentation and measurement, with a strong track record in smart sensors, autonomous systems, and low-power technologies. He holds a PhD in electronic engineering and has focused his scientific activity on advanced sensing systems, wireless sensor networks, and innovative solutions for complex environments.

Throughout his career, he has worked on multiple international research projects addressing challenges in environmental monitoring, energy efficiency, and the integration of intelligent systems into real-world applications. His contributions include the development of autonomous devices capable of operating in harsh conditions, as well as energy harvesting solutions.

His research also extends to bioinspired systems and the integration of electronic technologies with natural systems, exploring new ways to design sustainable solutions. He is the author of numerous scientific publications in instrumentation, sensors, and intelligent systems, and actively participates in international initiatives related to the transition toward greener and more efficient technologies.
