Introduction
Full Bio Sketch
I received my degree from the Department of Control and Measurement at Kyungil University in 2005. I have been working on the design of non-contact power supply devices (3kW 350kW wireless power transmission) at SESS for 8 years since 2005. I have designed electric and magnetic field designs and power conversion/transmission using impedance matching. I am currently a senior researcher at Kyungchang Industrial Co., Ltd. and have been designing automotive controller hardware and automotive sensors for 12 years. My research interest is the development of sensors using the magnetic field of permanent magnets.
Research Topic
I am interested in the sensor structure of the HALL sensor, so I studied the principle implementation of the HALL Effect and the magnetic field detection structure. I am interested in the overall IC design related to product configuration through magnetic field detection preprocessing (magnetic field detection of permanent magnets), optimization using MCU (filtering, amplification, modulation, external input parameters, etc. of the detected magnetic field), and postprocessing (user interface) of the detected signal.
When developing various sensors utilizing Hall sensors, we propose methods and standards for shielding against external magnetic fields and research stable shielding structures. We define and characterize the peripheral components of Hall sensors, consider the magnetic permeability of different shielding materials, and examine how internal and external magnetic fields are affected by the magnetic material layout. This study aims to propose a design direction that considers the characteristics of Hall ICs. External magnetic fields are the greatest threat and variable when developing sensors utilizing Hall ICs. We clarify methods for overcoming this instability, the need for mechanical space, and the purpose of magnetic materials. We will approach this design in various ways, including focusing the magnetic field to increase it, distributing it evenly, and shielding to prevent external magnetic fields from infiltrating. Just as MCUs are used to produce desired results, we aim to define the design process for sensor development by leveraging mechanical concepts and data characteristics.
