Research Areas

Statement of Technical Interest
  • Power electronics systems and electric drives for propulsion, energy management, and efficiency improvements in transportation, particularly for electric, hybrid (including plug-in hybrid) and fuel cell vehicle systems.
  • Advancing the technology of more electric aircraft with high power density and high temperature power conversion systems and electric machines leading to electric/more electric air transportation.
  • Power conversion and intelligent energy management for renewable electric energy delivery for an efficient electric power grid (micro grid/local) integrating highly distributed and scalable alternative power sources such as solar, wind, fuel cell, etc. 
  • Hybrid power generation systems for transportation and stationary power generation: fuel Cell, solar and wind; solar and fuel cell; solid oxide fuel Cell and turbine generator. The use of hybrid fuel systems for on board-power generation in airplanes and ships will increase the efficiency of power generation and reduce the emissions.
  • My interest is to put many of the innovative technologies to greater use by direct/indirect application in practical systems and commercialize these technologies for practically reducing the emissions, improving the energy efficiency, and for the development of sustainable energy resources.

News Articles

Prof Hopes Efficiency Research Saves Energy and Resources
Dr. Kaushik Rajashekara was an advocate of energy efficiency in vehicles before the concepts of renewable energy and lower emissions were popular. So while spending most of his career in industry, he made time to teach by giving more than 100 invited presentations in more than 40 countries. After years of working with companies such as Asea Brown Boveri, General Motors Corp., Delphi and Rolls-Royce Corp, Rajashekara has joined the faculty of UT Dallas as a professor of electrical engineering and mechanical engineering in theErik Jonsson School of Engineering and Computer Science. He is also holder of the Distinguished Chair of Engineering. In 2012 Rajashekara was elected to the National Academy of Engineering, the nation’s most prestigious organization recognizing engineering achievement, for his contributions to electric power conversion systems in transportation. From 1996 to 2012, Rajashekara was also an adjunct professor at the Purdue School of Engineering and Technology at Indianapolis. Rajashekara joined The University of Texas at Dallas this fall.
