This seminar is part of the Jones Seminars on Science, Technology, and Society series

The growing demand for energy will result in dramatic changes to the way we generate and manage energy. This provides unprecedented motivation to explore technologies that can facilitate more efficient energy conversion, reduced consumption and waste, and support lower carbon energy sources. This talk will present a research framework for next-generation electronics for energy efficiency that merges efforts in highly-integrated power electronics, communications electronics, and embedded systems techniques. Future research areas include applications in automotive, energy storage, and distributed energy generation. Research themes include resonant and digital techniques that leverage high-energy-density passives and deep integration in modern semiconductor technologies. A commercial effort in distributed power management for photovoltaic systems will be discussed that combines efforts in power electronics, power-line communications, and networked instrumentation. This effort includes development of a novel resonant switched-capacitor power converter that can achieve effective conversion efficiency of 99.5% and can substantially improve lifetime energy capture in photovoltaic systems.

About the Speaker

Dr. Jason Stauth received his MS/PhD from U.C. Berkeley in 2008 and his Bachelor of Engineering degree from Dartmouth in 2000. From 2000 to 2003 he was an Integrated Circuit Designer at Allegro Microsystems in New Hampshire. At Allegro he designed or co-designed several product families that achieved widespread commercial adoption including the ATS645 family of engine timing and wheel speed sensors, and the ATS750 family of magnetic current sensors. He also designed the A1320 family of linear hall-effect sensors that was selected as a finalist for the EDN Innovation award in 2005. At U.C. Berkeley Dr. Stauth explored a range of circuit architectures and techniques to reduce energy consumption of high-datarate wireless transmitters. His academic contributions included theory and design of high-bandwidth dynamic and hybrid voltage regulators, high frequency DC-DC converters, and a framework to study the effects of power supply noise on linear RF amplifiers. He also explored techniques in resonant power conversion applied to RF power amplifiers and developed a new CMOS polar transmitter with direct-digital amplitude modulation. In 2008 he co-founded QVSense Inc and operated as Chief Technology Officer (CTO) until QVSense was acquired by Solar Semiconductor Inc in 2009. At QVSense and continuing as Director of Hardware Engineering at Solar Semiconductor, Dr. Stauth developed new techniques in distributed power management for on- and off-grid renewable energy systems with particular focus on providing basic electrification, lighting, and telecommunications services to rural-developing regions.
