12th International Forum on Embedded MPSoC and Multicore
July 9-13, 2012, Québec, Canada
Speaker:Tohru Ishihara, Kyoto University, Japan
Title:A Power Management Technique for Energy Harvesting Embedded Systems
Energy harvesting is getting increased attention not only in wireless sensor network applications but also in consumer embedded applications. In energy harvesting embedded systems, it is important to maintain high efficiency when using energy generation sources. This high efficiency can be obtained by a high generating efficiency or a high transferring efficiency. Conventional maximum power point tracking (MPPT) techniques do not consider the transferring efficiency in a multiple load system. In this talk, we discuss a technique for improving the energy transferring efficiency by minimizing the power losses in DC-DC converters and chargers of the system with considering the power consumptions in multiple loads.
Tohru Ishihara received his Dr.Eng. degree in computer science from Kyushu University in 2000. For the next three years, he was a Research Associate in the VLSI Design and Education Center, the University of Tokyo. From 2003 to 2005, he was with Fujitsu Laboratories of America as a Research Staff of an Advanced CAD Technology Group. From 2005 to 2011, he was with Kyushu University as an Associate Professor. In April 2011 he joined Kyoto University, where he is currently with the Dept. of Communications and Computer Engineering. His research interests include low-power design methodologies and power management techniques for embedded systems. Dr. Ishihara is a member of the IEEE, ACM, IPSJ and IEICE. He has served on program committee of numerous conferences such as CODES+ISSS, DATE, and ISLPED.
