Biography: Prof Teng Long has been appointed Lecturer at the University of Cambridge in 2016, then Associate Professor in 2021 and Full Professor in 2022. He established the Advanced Power Electronics Laboratory in the Department of Engineering. 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 2017, Prof Long has been awarded more than £3 million research grants where half are funded by the UK government and the rest directly from industries. Prof Long has built strong connections with industrial partners including the SAIC Motor, Dynex Semiconductor, STMicroelectronics, Siemens, CBMM, NIO, CRRC, Wuxi SES.

Prior to joining Cambridge, he worked for General Electric where he has played an important role in many projects such as the first transformer-less all electric oil-platform supply vessel, the first large scale all electric warship, and the first electromagnetic aircraft catapult demonstrator. Prof Long established the EPIC Tech Ltd, a start-up company specializing high density power modules. Since inception, the company has raised several tens of million RMB venture capital and launched a few products. To date, Prof Long has more than 120 academic papers and he is the inventor of 7 international patents. Prof Long received the B.Eng. from the Huazhong University of Science and Technology, China, the first class B.Eng. from the University of Birmingham, UK in 2009, and the Ph.D. from the University of Cambridge, UK in 2013. Prof Long is a Chartered Engineer registered with the UK Engineering Council.

Abstract: Power electronics is ubiquitous in the energy system, nearly 80% of the world’s total electrical power or more than 12 billion kilowatts on average is being processed by power electronics based power converters in every hour of every day. From renewable energy to power supplies, from transport electrification to smart grids, every Watt is converted and controlled by power converters several times from the end to end. In quest of high performance and sustainability of power electronics, we will demonstrate a new design paradigm for power converter systems by means of structural and functional integration with consideration of circularity at the design stage. We introduce a smart control method which exploits electroluminescence from the semiconductor physics to empower a desirable soft-switching control for a significant increase of efficiency. This smart control is, accurate, robust, self-adaptive, and has EMI immunity. Instead of the linear design process using available components, we will cohesively design novel power electronic and passive component packages oriented from the system requirement. The novel packaging design takes new structures, materials, and fabrication/assembling technologies to advance their performance as well as enable their reusability and recyclability for their ‘another life’ and ‘after-life’. New design concept and deliverables enable reusability, repairability, recyclability of most of parts. In consequence, an unprecedented performance is expected, and the circular power electronics is enabled.
