2004, M.S. degree from Seoul National University, South Korea in 2006, respectively both in Electri-

Computer Engineering Department at The University of Akron, Ohio. He has more than 70 peer-

reviewed papers (published/pending) in IEEE journals and conference proceedings, seventeen patents

(registered/pending/provisional), and one co-authored book. He was with Toshiba International Co. as

R&D engineer on electric machine drive system from 2009 ~ 2012 and LG Electronics as communi-

Due to environmental issues such as global warming and air pollution, the demand for green energy system has been dramatically increasing in the world energy market. Electric motors and power electronics system play a vi-tal role in green energy system in applications to hybrid and electric vehicle (HEV/EV), alternative/renewable en-ergy generation system, more electric aircraft, Oil and Gas equipment, etc where the reliability is one of the criti-cal issues. Nowadays, almost all electric energy systems are equipped with an onboard diagnosis system and fault tolerant / recovery capability. This system has been used for warnings and monitoring critical failures. If a problem or mal-function is detected, then the diagnosis system sets a malfunction indicator light that is readily visible to the op-erator on the dashboard to inform that a problem exists. This health monitoring system is a valuable tool that as-sists in the service and repair by providing a simple, quick, and effective way to pinpoint problems by retrieving vital diagnostics. This presentation provides semi in-depth degradation analysis and fault diagnosis of (i) general electric motor and (ii) power electronics system, and (iii) the brief overview of the PI’s current and related spon-sored or pending projects.
