IET Auckland Local Network successfully hosted a special lecture titled “Beyond AI – The Next Technological Revolution: Cryogenic Power Electronics for Superconducting Systems” on 14 April 2026 at the Fickling Convention Centre, Mt Roskill, Auckland. The event brought together engineers, researchers, industry professionals, and university students to explore emerging technologies beyond artificial intelligence, with a strong focus on superconductivity and cryogenic power electronics.
The evening commenced with a welcome and introduction by Timothy O'Brien, who, as a former student of the speaker, introduced the session and set the context for the lecture. The lecture was delivered by Duleepa J. Thrimawithana, Associate Professor at the University of Auckland, who provided deep insights into superconducting systems and the enabling role of cryogenic power electronics. He discussed how these technologies are critical for applications in transportation, energy systems, electric aviation, and aerospace, and presented collaborative research involving the University of Auckland, Victoria University of Wellington, University of Cambridge, and University of Canterbury.
During the lecture, key technical insights were shared, including the behaviour of GaN HEMTs at cryogenic temperatures and the development of a cryogenic buck converter achieving efficiencies greater than 99%, demonstrating significant progress toward the practical implementation of superconducting power systems. The presentation also highlighted the strong collaboration between academia and industry across both domestic and international partners, as well as real-world applications of the research and the successful spin-out companies emerging from this work.
Warren McLuckie, Chairperson of the Institution of Engineering and Technology Auckland Local Network, delivered the vote of thanks and closing remarks. He reflected on the value of engaging with cutting-edge academic research that is often not easily accessible within industry. The event concluded with networking over refreshments, including finger foods and drinks, providing an excellent opportunity for professional engagement and discussion among attendees.
The lecture was well received and reinforced the IET Auckland Local Network’s commitment to delivering high-quality technical events that bridge academic research and industry practice while showcasing emerging technologies shaping the future of engineering.
