In this webinar, Daniel Ríos will present the design and experimental validation of high-frequency three-phase LLC converters developed for next-generation aircraft DC power systems. The talk will cover resonant converter design, integrated planar magnetics, and innovative wye-delta transformer architectures that enable   compact 1 MHz operation with efficiencies exceeding 96%.

The webinar will highlight how wide bandgap (WBG) technologies, particularly Gallium Nitride (GaN), are enabling unprecedented power densities and switching frequencies, making them a key technology for future aerospace electrification. Attendees will gain insight into the challenges of designing high-performance resonant converters and the opportunities they create for More Electric Aircraft (MEA) and other demanding power electronics applications.

Name / Surname	Daniel RIOS LINARES
Organisation / University	Universidad Politecnica de Madrid
Title in the Organisation	Assistant Professor
Role in ALL2GaN Project	Use Case 4 Researcher
Academic Background	Electrical and Electronics Engineering
Key Publication(s)	Ríos Linares et al., “High-Gain High-Frequency Three-Phase LLC Resonant Converter Design Based on the Wye–Delta Transformer for Aircraft Applications,” IEEE TPEL, 2024 Mo et al., “Toward Embeddable Digital Twins: A Voxel-Based Approach for Power Converter Temperature Monitoring,” IEEE JESTPE, 2025
Why GaN? What excites you about the project?	GaN enables MHz switching in power electronics, reducing magnetic size and weight while maintaining high efficiency. In All2GaN, we combine GaN, advanced magnetics, and new converter topologies to unlock much higher power densities for more electric, efficient aircraft, making GaN not just the best option, but in some cases the only viable one.
What is the biggest challenge in making power electronics greener?	Knowing the trade-offs, everything is important at the same time: efficiency, cost, material sustainability, size, weight, material usage... but in what amount?
