Abstract
University of Kentucky presents the concept of smart coils for electric propulsion AC motors. For
more and all-electric propulsion systems, high power density, high efficiency, and high reliability are the
most critical features. To enhance the efficiency and power density of propulsion systems through
minimizing the size of passive components and thermal management (cooling) systems, the emerging
ultrafast switching devices (e.g., SiC MOSFETs) are getting attractive compared to the fast switching
devices (e.g., Si IGBTs). However, steep switching capability using ultrafast switching devices can
cause reflected waves in electric propulsion systems even with short cable lengths between the switches
in a drive and electric motors. Such reflected voltage waves, if not mitigated, can cause severe voltage
stress on the motor winding insulation. This project aims to develop smart coils’ technology for
propulsion motors, which adaptively changes the winding surge impedance by manipulating the high-
frequency component of the line voltages with steep voltage changes. This collaborative research
can significantly impact mobile energy technologies such as electric vehicles, more electric aircraft, and
electric shipboards, where power density, efficiency, and reliability are the critical design features.
