Presentation Summary

Gallium Nitride (GaN) is creating an innovative shift throughout the power electronics world. For decades silicon-based semiconductors have been the leaders in converting energy to power, but we are now are now reaching the limit on how much silicon can do. GaN is on the rise to replace silicon as the backbone of power electronics especially in the automotive world for electric vehicles. GaN is meeting the growing needs with better power systems efficiency, performance and systems cost. This session will cover the technical aspects of how GaN is more efficient and will continue with a discussion about which specific applications can benefit from GaN along with some of the challenges the technology is facing.

Speaker Biography (Jim Witham)

Jim Witham's career has focused on bringing new technology, like GaN Systems' world's best performing power transistors, to the Electronics market.
Witham joined GaN Systems from Neoconix, a manufacturer of high density, miniature connectors. As CEO of Neoconix, he successfully implemented strategic changes which dramatically increased revenue and resulted in the company's acquisition by Unimicron Technology. Prior to Neoconix, Witham was CEO of Fultec Semiconductor, where his team made circuit protection devices using high voltage silicon, silicon carbide and gallium nitride (GaN) transistors. Fultec was acquired by circuit protection market leader Bourns. Witham has also held VP Sales & Marketing positions at Aegis Semiconductor, a tunable filter semiconductor manufacturer and Genoa, a semiconductor optical amplifier manufacturer.
Other notable career highlights include senior executive positions at Raychem, including General Manager of the Raychem Interconnect Division and Director of Asia Sales & Marketing, based in Japan, for the Raychem Circuit Protection Division. As an Engineering Specialist at General Dynamics' Space System Division during the eighties, Witham designed fluid systems for the Space Shuttle and was on Mission Control for interplanetary missions. Witham holds an MBA from Harvard and both M.S. and B.S. with distinction in Mechanical Engineering from Stanford.
