Common-mode Noise Reduction for AC Motor Drives

by Dr. Dong Jiang
Huazhong University of Science and Technology (HUST)

Abstract: Common-mode (CM) noise caused by three-phase PWM converters is a serious threat for AC motors, not only by adding EMI problem, but also causing failure of motor insulation and bearing. CM filter is usually needed for CM noise reduction, but significantly increasing the system complexity and weight. This presentation shows series of work for CM noise reduction for AC motor drives through the modulation methods. First, modification of PWM methods can reduce the CM voltage for regular three-phase VSI based motor drive, and reduce the CM noise together with the CM loop impedance. Then, modulation with more complex topologies can further reduce the CM noise for motor drives. All the introduced methods are supported by experimental results, and with published journal and conference papers and published patents/patent applications.

Bio: Dr. Dong Jiang received his B.S and M.S degrees in Electrical Engineering from Tsinghua University in 2005 and 2007. He began his PhD study in Center for Power Electronics Systems (CPES) in Virginia Tech in 2007 and was transferred to University of Tennessee with his advisor in 2010. He received his PhD degree in University of Tennessee in Dec. 2011. He was with United Technologies Research Center (UTRC) in Connecticut as a Senior Research Scientist/Engineer from Jan 2012 to July 2015. He joined Huazhong University of Science and Technology (HUST) in China as a professor in July 2015. Dong Jiang’s major research area is power electronics and motion control, with more than 50 published journal and conference papers and 18 patents/patent applications in this area. He is a senior member of IEEE and associate editor of IEEE Transactions on Industry Applications.
