Electromagnetic Compatibility and Electromagnetic Interference in Inverter Dominated Grids

Dear Colleagues,

The increasing presence of power electronic converters across a wide range of applications is reshaping the electromagnetic environment in which modern electrical systems operate. While these converters are essential for achieving energy efficiency, flexibility, and the integration of renewables, they also introduce significant challenges related to electromagnetic compatibility (EMC) and electromagnetic interference (EMI).

From fast DC chargers to distributed storage units and advanced renewable systems, power converters rely on high-frequency switching that inherently generates conducted and radiated emissions. These emissions can interfere with nearby equipment, disrupt communication networks, or cause malfunction in sensitive electronics. Moreover, the simultaneous operation of multiple converters—often of different types and manufacturers—can lead to complex coupling phenomena, resonances, and unintended noise propagation throughout installations, thereby compromising grid stability.

EMC and EMI issues, in this context, are no longer confined to individual devices but extend to the entire electromagnetic ecosystem in which they function. The growing density of power electronics, the use of long cable runs in renewable installations, the modular system architectures, and increasing connectivity through digital interfaces (e.g., vehicle-to-grid systems or smart microgrids) all contribute to a more intricate and dynamic EMI scenario.

This Topic will gather researchers, engineers, and industry experts to address the emerging EMC/EMI challenges in modern power converter applications. Particular focus will be given to the following:

• Mechanisms of electromagnetic noise generation and propagation in conversion systems;
• Modeling and simulation techniques for EMC in time and frequency domains;
• Advanced filtering, shielding, and layout strategies for EMI mitigation;
• EMI impact on embedded control systems and digital communication interfaces (e.g., CAN, Modbus, Ethernet);
• EMC testing procedures and applicable standards for energy-related converters;
• Co-design approaches integrating electromagnetic considerations in hardware and firmware;
• Practical insights and case studies from sectors such as e-mobility, smart grids, and energy storage.

Submissions that combine theoretical analysis with experimental validation and real-world application are particularly encouraged. This Topic will promote a comprehensive yet application-oriented perspective on EMC challenges and foster the development of effective and sustainable solutions for next-generation power electronic systems.
