Biography

Hirofumi Akagi, professor and vice dean of the school of engineering at the Tokyo Institute of Technology, is a leading researcher in power conversion systems and their application to industry, utility and transportation. He has pioneered the theory of instantaneous reactive power in three-phase circuits, referred to as the “p-q theory,” which has been applied to power conversion systems and active filters for power conditioning. In addition, Dr. Akagi invented hybrid active-passive filters, the system concept and operating principle of which have been applied to the hybrid active-passive filter used in the Yamanashi test line for Japan’s super high-speed, magnetically levitated train system. An IEEE Fellow, Dr. Akagi holds nine patents – with five more pending, and has authored or co-authored more than 70 IEEE Transactions/Journals. Dr. Akagi has received four IEEE Transactions Prize Paper Awards, the IEEE William E. Newell Power Electronics Award and the IEEE Industry Applications Society Outstanding Achievement Award.
