In early 2020, we launched the SIMULIA Champions program. The 2020 SIMULIA Champions are the inaugural team of brand ambassadors, whose expertise and passion position them to advance the future of simulation technology. In this series of blogs, we introduce some of our individual SIMULIA Champions, finding out more about their history – and future – with the technology.
Hycksu Kweon is a Principal Research Engineer at Hyundai Mobis, a South Korean company that develops and produces electronics for automobiles. Kweon is in charge of electronic analysis, and he and his team are currently working to reduce noise in eco-friendly cars. Despite the fact that electric vehicles are overall quieter than their internal combustion engine counterparts, they still suffer from the same noise sources as traditional cars, such as tire and road noise, wind noise, gear whine and HVAC noise.
Kweon has worked with CST products for 10 years, and currently uses CST Studio Suite/Microwave Studio software. He has been doing EMI interpretations for 20 years, and his current analysis mostly focuses on cables and grounds. Working with five colleagues, Kweon was able to design noise reduction measures in the early stages of vehicle development.
“We have established a process so that we can proceed with this development only by always calling analytical verification on the development process, and now we are applying that process well,” he says.
A physics major in college, Kweon pursued EMI analysis on the recommendation of a mentor. His study of physics has helped in his EMI career, which he will continue to develop because he believes that more EMI problems will occur in the future.
“Whether now or in the future, I think the EMI issue will always be the same,” he says. “It is a problem that always occurs in switching conditions.”
Kweon describes his greatest challenge as a case when he had to improve the EMI of an inverter, which is a power electronics product that controls motor speed by converting power using power semiconductors. It is an “indispensable” component in an eco-friendly car, he says.
“At that time, there were many cases of interpretation and improvement of problems for high-speed signals, but interpretation and improvement of high power and low frequencies were difficult to obtain examples and help,” he says. “Analysis and EMI improvement for this inverter was the biggest success. The switching noise generated by the inverter affected the entire drive system.”
Kweon is happiest when he is working out problems with his colleagues.
“The knowledge and know-how that I have, the sparkling ideas of my colleagues…these things make me come to work and make me excited,” he says.
Outside of work, Kweon enjoys spending time with his family and golfing, which he describes as “healing.” He tries to do his best in everything and to continue learning new things; currently he is studying automation and is interested in automating simulation through Python coding. Kweon is an iNARTE EMC Engineer and an EMC Technical Committee member.
SIMULIA is pleased to welcome Hycksu Kweon into the 2020 SIMULIA Champions program and excited to continue working with him in the future. Stay tuned to the blog to learn more about our other 2020 SIMULIA Champions.
