Dr. Angelo Gattozzi

Function: Research Associate

Biography
Dr. Gattozzi joined UT-CEM in 2000. His main focus is on electric power system modeling and simulation, smart-grid/micro-grid systems with renewable energy resources, the electric system of the DDG51 class Navy destroyer and of some Army Tactical Operating Centers, energy harvesting, resonant converters, high speed motors/generators, magnetically active composites for flywheel energy storage, and power modules for the electric gun program,
Prior to joining UT-CEM, Dr. Gattozzi was lead R&D electrical engineer at the Lincoln Electric Company in Cleveland, Ohio, where he was responsible for the development of a complete line of induction motors, 1-500 HP, which achieved the highest efficiency levels in the industry. He was previously an adjunct associate professor of Electrical Engineering at Case Western Reserve University in Cleveland, Ohio, in Electromagnetic Theory, Electromechanical Energy Conversion, and Microwave Theory and Techniques. There he developed an early prototype (1972) of digital storage oscilloscope with 100 MHz bandwidth, and an Ashby-Jephcott interferometer for plasma gun diagnostics.
Dr. Gattozzi was co-founder of Tyler Research and Engineering, a consulting firm and laboratory, where he led many R&D projects sponsored by industry and Government Agencies, among which: the first computer program on record for calculating the performance of superconducting machines, a four axes positioner for sheet steel processing, electromagnetic stirring for continuous steel casting, an improved atmospheric moisture sensor, ultrasonic sensors, experimental characterization of electronic assemblies for automotive, aircraft, and marine applications, a low-pass active filter with 0-25.5 kHz band and 70 dB attenuation at 27.5 kHz for satellite communication, and many others.
He began his career as an electrical engineer at Reliance Electric Co.’s Research and Development Center in Cleveland, Ohio, where he was co-developer of the first permanent magnet motor in the U.S.A. based on rare earth magnet technology, and of several computer programs for calculating machine performance still in use today.
