How Electromagnetic Compatibility of Power Electronic Systems Contributes to “Climate Action”

AAU researcher has taken on a challenge to improve power electronics systems compatibility used to deliver and control electrical power in the electric grid and found in our numerous everyday electronic devices.

New technologies demand new solutions

The continuous growth of electricity demand worldwide and the global shift of energy paradigm to carbon-free technologies (e.g., 100% of renewables by 2030 in Denmark) have significantly increased the demand for power electronic systems.  Power electronic systems are a key enabler in transition to green technologies, from renewable generation like wind/solar power, electric vehicles down to laptops and mobile phone chargers and lighting.  To ensure development and transition to green technologies, compatibility of power electronic systems must be met. 

Associate Professor Pooya Davari is at the forefront of a dedicated research effort in the Department of Energy Technology at Aalborg University to create compatible power electronic systems that can support this development. At the core of this research is the electromagnetic compatibility (EMC) of the power electronic systems, which allows the electronics to function properly without causing intolerable electromagnetic interference (EMI) and disturbance to any other devices in the same environment.

Pooya Davari has led a research project in developing systematical control and modeling methodologies for tackling harmonic and electromagnetic compatibility challenges in power electronic systems. His research is targeted at predicting electromagnetic interferences early in the design phase and developing mitigation methods and power electronic systems that will enable our everyday electronic devices to comply with the international standard regulations. The Electromagnetic Compatibility Laboratory at the Department of Energy Technology is able to provide innovative solutions and support companies saving huge cost and time for their product design and development before a planned production is set to start. The project is carried out in close collaboration with a number of companies:  FORCE Technology, Danfoss, Grundfos, Vestas, Dansk Energi, Nordic Power Converter ApS (NPC), Kamstrup A/S, PowerCon A/S, Bitzer A/S, Pascal A/S and OJ Electronics A/S.

Recognition from other researchers

For his research, Pooya Davari has received the 2020 IEEE EMC Society Young Professional Award, which is a tremendous recognition of his contribution in this research field.

 - The recognition of my contribution to “EMI and Harmonic Mitigation in Power Electronic Applications” is of significant importance to me as the EMI and EMC in power electronic applications have been dominated by the industry for many years. This award brings further national and international recognition to highly reputed Aalborg University. I believe, with the advent of new emerging technologies and high penetration power electronic based systems, it is time to put the old EMI/EMC cook books aside and look for more systematic and innovative approaches in order to speed-up deployment of electromagnetic compatible power electronic based applications which is quite vital to reduce carbon foot print, explains Pooya Davari.

Next research goals

Green transition includes extensive electrification of many sectors such as transportation and industry which further increases the power electronic systems demand. With massive penetration of power electronic systems, more disturbances and interferences are witnessed and are expected to appear on the electrical power grid. Therefore, new international standards are going to be released which can highly affect the electronics industry, and, as of today, no effective solution exists to comply with new coming standard requirements (i.e., 2-150 kHz frequency range). This can slow down the deployment of renewable energy systems and reaching green transition goals. In order to minimize the impact on industry, the Department of Energy Technology at Aalborg University is now specifically focusing on new energy and cost-effective solutions tackling the new coming EMC standard requirements.
