Sergio F. Barbosa is a Brazilian electrical engineer and academic known for work in power electronics, control systems, and applications to transportation and renewable energy. He has held positions at leading universities and industrial research laboratories, collaborating with international institutions on motor drive technologies and grid-connected converters. His publications and patents have influenced developments in electric vehicle propulsion, photovoltaic inverters, and energy storage integration.
Born in São Paulo, Barbosa completed primary and secondary studies in São Paulo before entering higher education at the University of São Paulo, where he earned a Bachelor of Engineering in Electrical engineering and a Master’s degree focused on power converters. He pursued doctoral studies at the Massachusetts Institute of Technology, conducting dissertation research that bridged power electronics and control theory under advisors with links to MIT Lincoln Laboratory and collaborating with researchers from Stanford University and University of California, Berkeley. His formative training included exposure to research groups associated with IEEE Power Electronics Society and technical exchanges with teams at General Electric and Siemens.
Barbosa began his academic career with faculty appointments at the Federal University of Rio de Janeiro and later returned to the University of São Paulo as a senior professor and laboratory director. He served visiting researcher stints at Massachusetts Institute of Technology, ETH Zurich, and Imperial College London, and held industry research positions at IBM Research and Siemens Corporate Technology. His research groups collaborated with national laboratories such as National Renewable Energy Laboratory and industrial partners including ABB, Bosch, and Volkswagen Group on electrification and converter control. He has been active in professional organizations including the Institute of Electrical and Electronics Engineers and the International Council on Large Electric Systems.
Barbosa's major contributions address modulation techniques for voltage-source inverters, sensorless control strategies for permanent magnet synchronous motors, grid-forming converter controls for microgrids, and algorithms for maximum power point tracking in photovoltaic systems. He authored influential articles in journals such as IEEE Transactions on Power Electronics, IEEE Transactions on Industrial Electronics, and IEEE Transactions on Sustainable Energy, and contributed chapters to edited volumes published by Wiley and Springer. His work on deadbeat control, model predictive control, and robust observer design has been cited alongside foundational studies by researchers at CentraleSupélec, Politecnico di Milano, and Tsinghua University. He holds patents in multilevel converter topologies and battery management methods that have been licensed to companies in the automotive industry and renewable energy sector.
Barbosa was elevated to IEEE Fellow for contributions to power conversion and motor drive control, and received national recognition via the Ordem Nacional do Mérito Científico. He earned multiple best paper awards from conferences organized by the IEEE Power Electronics Specialists Conference and the IEEE Energy Conversion Congress and Exposition. His laboratory won institutional grants from agencies such as FAPESP and CNPq, and he received visiting scholar fellowships from DAAD and the Royal Society for collaborative projects with University of Cambridge and RWTH Aachen University.
As a professor he taught courses at undergraduate and graduate levels at the University of São Paulo and the Federal University of Rio de Janeiro on subjects including power electronics, electric drives, and control systems. He supervised doctoral and postdoctoral researchers who later joined faculties at institutions like Universidad Nacional Autónoma de México, University of Toronto, Monash University, and KTH Royal Institute of Technology. Barbosa participated in curriculum development efforts with accreditation bodies such as ABET and national educational agencies, and organized short courses and tutorials at events hosted by the IEEE Industrial Electronics Society and the IEEE Power & Energy Society.
Major projects led or co-led by Barbosa include collaborative programs on electric vehicle propulsion systems with Volkswagen Group and Embraer, grid integration studies with National Grid and Operador Nacional do Sistema Elétrico (ONS), and multinational research on high-efficiency inverters with teams from Fraunhofer Institute and CEA (French Alternative Energies and Atomic Energy Commission). He co-coordinated EU-funded research consortia involving partners from University of Bologna, Delft University of Technology, and Chalmers University of Technology, and secured industrial partnerships with Siemens, ABB, and Schneider Electric to translate laboratory prototypes into demonstration systems for urban transit and distributed generation.
Barbosa is married with two children and maintains ties to cultural institutions in São Paulo, including collaborations with the Museu de Arte de São Paulo on STEM outreach. His legacy includes a generation of engineers trained in applied power electronics, a body of publications and patents influencing electric mobility and renewable integration, and continued advisory roles on technical committees for IEEE Standards Association and national energy policy advisory boards. He is remembered in professional circles for bridging academic research and industrial application across Latin America, Europe, and North America.
