Session Abstract
Power electronic systems are essential to modern energy conversion, enabling efficient regulation and distribution of electrical energy across various applications. As electrification and digitalization advance, power electronics play an increasingly crucial role but inherently generate electromagnetic interference (EMI), which can degrade performance and compromise reliability. Ensuring electromagnetic compatibility (EMC) is critical to maintaining functionality, safety, and regulatory compliance.
This tutorial explores EMC challenges in power electronics, covering EMI sources, propagation mechanisms, and mitigation strategies. It introduces an open research and teaching platform for DC-DC converters, demonstrating FPGA-based implementation for hands-on EMC design. Additionally, the session examines conducted emission aggregation in smart grids, modeling techniques for interference propagation, and statistical approaches such as Pearson’s Random Walk for predicting EMI behavior in multi-converter systems. Advanced EMI filtering solutions for evolving power applications, including aerospace motor drive systems, will also be discussed, with a focus on optimizing weight, efficiency, and compliance with industry standards.
