Recently, the IEEE (Institute of Electrical and Electronics Engineers) Industrial Electronics Society (IES) Chapter was established at Tianjin University. Organized by the School of Electrical and Information Engineering of Tianjin University and the Brain-inspired Computing and Intelligent Control Research Center, the inaugural meeting specially invited Prof. Joachim Holtz from Wuppertal University, a world-renowned expert in electrical and electronics engineering, IEEE life fellow, recipient of the IEEE Lamme Gold Medal and the IEEE Third Millennium Medal, to make an academic visit.
Prof. Holtz giving a speech
At the inaugural meeting, Prof. Joachim Holtz congratulated Tianjin University on the establishment of the IEEE Industrial Electronics Society Chapter and delivered a lecture titled “Energy Efficiency for High-Power Electrical Drives” to an audience of more than 100 teachers and students, among them Prof. Liu Chunhua from City University of Hong Kong, researcher Ma Xiaoliang, Prof. Wei Xile, Prof. Deng Bin, Associate Prof. Zhang Yun and Dr. Gao Shuang from Tianjin University.
Prof. Holtz had in-depth exchanges with the attendees
As an international authoritative scholar famed for his achievements in electronic energy conversion and AC drive, and a recipient of the Lamme Gold Medal, honored as “Nobel Prize in the fields of electric motor and electronics”, Prof. Holtz is the inventor of three-level inverter, Space Vector Pulse Width Modulation (SVPWM), sensorless control of Permanent Magnet Synchronous Motors (PMSM) and induction motors, etc. Many of his research results have set today's industrial standards. In this lecture, Prof. Holtz focused on high-power electrical drives, introduced innovations such as PMSM drives and inverter system predictive control from theoretical and practical perspectives, shared information on the development of mainstream high-power electrical electronics devices such as Insulated-gate bipolar transistor (IGBT), and thoroughly discussed strategies for improving energy efficiency.
After the lecture, Prof. Holtz had in-depth exchanges with the attendees on hot issues in the field of power electronics, as well as questions and technical difficulties encountered in related research projects. He also encouraged young researchers to open up their minds, seek breakthroughs and innovate by learning from outstanding research results and interacting with experts and mentors.
The establishment of the IEEE IES Chapter at the Tianjin University is of great significance for fully concentrating and exerting the research capability in the field of power electronics. The IEEE IES Distinguished Lecture delivered by Prof. Joachim Holtz not only gives researchers an insight into the state of the art of high-power electrical drives, but also promotes Tianjin University’s international cooperation regarding power electronics, laying a foundation for the long-term development of IEEE IES Chapter and boosting the advancement of industrial electronics.
