Title: Hyunchuel Kim: Electric Vehicle Transformer Inventor.
Introduction
Hyunchuel Kim is an inventor based in Gyeonggi-do, South Korea. His work includes transformer designs for electric vehicle power systems, with a focus on compact construction and efficient integration. He is associated with Atum Co., Ltd. and has 2 patents.
Latest Patents
Kim’s recent patent work includes two transformer designs for electric vehicles.
The “Transformer for LDC of Electric Vehicle” describes a plate-type primary coil that receives current from the vehicle’s high-voltage battery. Upper and lower secondary coil elements use magnetic induction to supply current to the vehicle’s electrical components. The arrangement is designed to reduce the transformer’s height and overall size.
The “Transformer for OBC of Electric Vehicle” features a housing and cover containing a plate-type primary coil and multiple plate-shaped secondary coils. The primary coil receives power from a charger, while the secondary coils independently generate induced current and deliver it to the high-voltage battery. The design aims to reduce product size and improve productivity.
Career Highlights
Kim’s patent portfolio addresses components used in electric vehicle power conversion. Both transformer designs use plate-shaped coils and compact layouts, applying related design principles to different vehicle charging and power-supply functions.
