EMI/EMC in Power Electronics - AAU Energy research group

About the Rearch Group

The inherent pulse energy conversion of power electronic converters leads to serious non-intentional harmonic emissions and electromagnetic interferences (EMI), which can cause the power grid to operate in an unpredictable and undesirable fashion.

Although EMI and power quality is a wide and very old field of study, extensive penetration of power electronic-based systems, development and emergence of wide band-gap (WBG) based converters and lack of low frequency EMI emission limits have brought new challenges in this field of study. 

Thereby, this research group focuses on foundation of unique research studies dedicated to maintaining power integrity of future electronic-based grid. The program also addresses generation, propagation and mitigation of noise emissions at device and system levels as well as improvement of power quality. Furthermore, the research activities in this program also includes measurement techniques and developing virtual-oriented tools for predicting EMI and power quality issues.
