| Session Abstract | ||
|
The rapid evolution of power electronics in various domains, including automotive, aerospace, and industrial applications, has brought electromagnetic compatibility (EMC) challenges to the forefront of design considerations. The conventional Electromagnetic Interference (EMI) mitigation techniques pose various constraints and to overcome these challenges, Active EMI Filters (AEFs) are gaining popularity. This workshop presents a unique opportunity to explore cutting-edge developments in Active EMI Filters (AEFs), a technology poised to revolutionize EMC solutions across multiple industries. Leading experts from renowned companies and research institutions will present their latest findings and innovations in both digital and analog AEF (DAEF and AAEF) technologies. At the forefront of the workshop, the presenters will provide insights into the general working principles of DAEF and AAEF. The workshop will cover various topics, ranging from fundamental principles to stability analysis to practical implementations in high-power applications. Moreover, some potential areas of improvement in these technologies for implementation in a variety of applications will be discussed as well. Attendees will gain insights into assessing system parameter’s impact on AEF performance in automotive eDrives, stability analysis techniques for optimizing insertion loss, and the latest trends in three-phase AC and DC motor drives. In the domain of Active Filtering, the real world applications and the placement of components in high power applications is overlooked. The presenters will showcase the implications of various system parameters on the performance evaluation of AEFs. Moreover, the challenges that hinder the implementation of DAEFs or AAEFs in various applications (aerospace, industrial and automotive) will be presented. The workshop also aims at showcasing advancements in standalone AEF ICs, offering reduced and cost optimized system solutions. Furthermore, it will explore the potentials of digital active filters for common mode EMI suppression in power electronic systems, providing a comparative analysis with traditional methods and outlining future development paths. A special focus will be given to the constraints and opportunities for high-power (50 kW) AEFs in aeronautical applications, addressing the critical need for weight reduction and cost-effective EMI solutions in aircraft electrification. By bringing together diverse perspectives from industry leaders and researchers, this workshop aims to encourage collaboration and drive innovation in AEF technology. Participants will have the opportunity to engage in discussions on overcoming current limitations, exploring new applications, and shaping the future of EMC solutions for nextgeneration power electronics. Active EMI Filtering is a growing field which addresses the ever-growing challenge of introducing sophisticated solutions. Presenting this topic at the conference will provide attendees with actionable insights and the presenters can also benefit from it, since variety of ideas will be discussed/shared during an open Q&A session. This workshop is an essential event for EMC specialists, power electronics engineers, and researchers looking to stay at the forefront of AEF technology and its transformative potential across various industries. | ||
