报告内容:

Inductive power transfer systems with active pick-ups, which are typically referred to as bi-directional IPT (BD-IPT) systems, not only improve system efficiency and flexibility, but also enables wireless Vehicle to Grid/Grid to Vehicle (V2G/G2V) services. These services, which are expected to become an integral part of future EV charging infrastructure, include the absorption of power variances produced by renewable energy sources, reactive power injection for grid voltage regulation and harmonics absorption for improved power quality. Overall, such services can further enhance the use of renewable energy sources, while also providing an additional revenue stream for EV owners. Consequently, there is a significant interest to develop novel technologies for BD-IPT systems that help lower the system cost, improve power transfer efficiency and provide greater spatial tolerance while also enabling the EV to provide services.

The first part of this presentation intends to introduce fundamental operating principles of a BD-IPT system. This will be followed by a summary of latest technologies developed by the power electronics research group at the University of Auckland. This discussion will include details of technologies such as hybrid compensation, boost active bridge (BAB) converter, integrated boost modular multi-level converter (IBMMC) and push-pull coupler array (PPCA). The presentation will conclude highlighting current research challenges and future directions.

个人简介:

Duleepa J. Thrimawithana, received his BE in Electrical Engineering (with First Class Honors) in 2005 and his Ph.D. in power electronics in 2009 from The University of Auckland, Auckland, New Zealand.

From 2005 to 2008, he worked in collaboration with Tru-Test Ltd. in Auckland as a Research Engineer in the areas of power converters and high-voltage pulse generator design. He joined the Department of Electrical and Computer Engineering at The University of Auckland in 2009 where he currently works as an Associate Professor. He has co-authored over 100 international journal and conference publications and holds 16 patent families on wireless power transfer technologies. In recognition of his outstanding contributions to engineering as an early carrier researcher, Dr. Thrimawithana received the Jim and Hazel D. Lord Fellowship in 2014. His main research areas include wireless power transfer, power electronics and renewable energy.
