“EV Market Expansion...Power System EMI is Fatal to Human Body and Vehicle Functions”
Sharing wireless charging noise reduction and wireless power transmission EMI/EMC response cases
As electrification of mobility accelerates, reliability issues and noise interference issues of high-power electric vehicles are rapidly emerging as industry challenges. Experts will deeply analyze and introduce the latest response technologies and real-world cases to share insights.
2024 e4ds Analog Day will be held at the Korea Conference Center on December 10th. This seminar, hosted by e4ds news and held every year around this time, has provided the latest trends and technology education for domestic EMI/EMC practitioners.
At this year's
2024 e4ds Analog Day , various sessions were held under the theme of 'EMI/EMC Response in Power Electronics: EMI/EMC for Wireless Power Transmission System Convergence and High-Reliability Automotive'.
Starting with the morning presentation on the causes and countermeasures of EMI in power systems by Professor Kim Ji-seong of KAIST’s Cho Cheon-sik Mobility Graduate School, the afternoon presentation will include: △ Q&A on a case study of EMI/EMC response in wireless power transmission systems by Professor Ahn Seung-young of KAIST; △ EMI/EMC standard/certification trends by Expert Committee Member Seong Gwan-yeong of the Korea Testing & Research Institute for Chemical Industry; △ Electromagnetic interference issues and EMI shielding in electrical components such as electric vehicles by Senior Researcher Yeon Gyu-bong of the Korea Automobile Research Institute.
By inviting EMI/EMC experts covering power systems, wireless power transmission, electrical components, and standards, it is expected to become a place for knowledge sharing where various Q&As can be deeply resolved in one place.
Professor Kim Ji-seong said, “Recently, the E-Mobility market, such as electric vehicles, has been expanding, and in these systems, the design of batteries and power systems is very important.” He added, “In particular, EMI noise generated in the power system can cause errors in autonomous driving functions or communication systems, and can also cause problems with human health.”
In this session, Professor Kim Ji-seong examines the main causes of EMI occurring in power systems and explains design measures to reduce them. In addition, it is expected that the latest EMI/EMC case study will be learned by introducing a case study in which EMI noise generated from a full-bridge inverter of a wireless charging system was reduced through system modeling and analysis.
