The need for speed in Space Power Electronics - 2021 Mars Society Virtual Convention

Speakers: Mohsen Marefat Babak Parkhideh Track Code: TE-2 Abstract: The adoption of post-silicon substrates for power electronics is a significant pathway to higher power density and better efficiency in electronics for space systems and stationary power facilities on the Moon and Mars. The transition to Wide BandGap (WBG) technologies has been faster and smoother than many predictions. Now is the time for power system designers to take full advantage of the inherent capabilities of the new materials: Shrink the size and increase robustness and reliability. Speed is the key design difference. While higher breakdown voltage and current capability are the first level advantage over Silicon, switching speed is the game-changer that allows smaller coils and inductors that result in significant size/weight reduction. However, fast switching characteristics (less than 10 nanoseconds for Gallium Nitride GaN) require designers’ attention to nuances and the use of new techniques for fault detection and fail-safe operation. This tutorial-style discussion aims to inform all Space Application enthusiasts of the latest developments in Power Electronics and the resulting advantages for near-term deployment. From the 24th Annual International Mars Society Convention, held as a Virtual Convention worldwide on the Internet from October 14-17, 2021. The four-day International Mars Society Convention, held every year since 1998, brings together leading scientists, engineers, aerospace industry representatives, government policymakers and journalists to talk about the latest scientific discoveries, technological advances and political-economic developments that could help pave the way for a human mission to the planet Mars. Conference Papers and some presentations will be available on www.MarsPapers.org For more information on the Mars Society, visit our website at www.MarsSociety.org #MarsSociety #MarsSocCon2021
