Dr Teng Long has been appointed Lecturer at the University of Cambridge in 2016. He established the Applied Power Electronics Laboratory (The Long Group) and he is currently leading a research team comprised of 3 Postdoctoral Research Associates and 8 PhD students. His research portfolio covers from power electronic devices to power converters to drive and power systems, mainly for transport electrification and renewable energy applications. Since his Lectureship, Dr Long has been awarded more than £2.5 million research grants where half are funded by the UK government and the rest directly from industrial sponsors. Dr Long has built strong connections with industrial partners including the SAIC Motor, Dynex Semiconductor, STMicroelectronics, Siemens, CBMM, CRRC, Wuxi SES, Huawei, NIO, etc. 

Prior to joining Cambridge, he has worked for General Electric (GE) where he has led or played an important role in many rewarding projects such as the first transformer-less all electric oil-platform supply vessel, the first large scale all electric warship (Type 45 Destroyer), and the first electromagnetic aircraft catapult demonstrator.

To date, Dr Long has more than 40 academic papers published at international journals and he is the inventor of 5 international patents. Dr Long received the B.Eng. from the Huazhong University of Science and Technology, China, the first class B.Eng. (Hons.) from the University of Birmingham, UK in 2009, and the Ph.D. from the University of Cambridge, UK in 2013. Dr Long is a Chartered Engineer registered with the UK Engineering Council.



Wide Band Gap (WBG) devices such as Silicon Carbide (SiC) and Gallium Nitride (GaN) have been widely considered as the next generation of power semiconductors. However, to unlock the full potential of SiC and GaN devices, design of power converters principles need to be revisited and modified. In this talk will give introduction of selected novel technologies in switching modulation, magnetic components, and converter integration which transfer the advantageous physical properties of WBG devices into high efficiency and high power density energy conversion. Emerging applications enabled by WBG devices such as wireless power transfer for EVs and ultra-high power density 48V DC systems for datacentres will also be introduced. Examples and results used for the aforementioned technologies and applications are exclusively from the Applied Power Electronic Laboratory in Cambridge.
