Charis Demoulias was born in Katerini, Greece on 23/07/1961. He received the Diploma on Electrical Engineering and the Ph.D degree from the School of Electrical and Computer Engineering (ECE) of the Aristotle University of Thessaloniki, Greece, in 1984 and 1991 respectively.


After his military service, he cofounded in 1992 the consulting company Alteren SA with which he designed, supervised and implemented numerous projects on: electrical energy conservation, stand-alone PV and hybrid Diesel-PV systems, grid-tied PV systems, passive power harmonic filters, storage of electrical and thermal energy, lighting and lighting-control systems as well as conventional electrical-mechanical installations.

He joined again the ECE of Aristotle University of the Thessaloniki, Greece, in 2002 as Lecturer. Currently he is Associate Professor with ECE teaching Power Electronics, Electrical Machines and Electric Motion Systems in the under graduate courses. He also teaches Power Quality in the post graduate courses of ECE. He is the author of the book “Electrical Machines-Synchronous Machines” (in Greek).

He has supervised more than 70 diploma theses while the results of 13 of them have been published in scientific journals and conferences.

His research interests are:

  • Power quality (harmonic distortion of currents and voltages, voltage and load asymmetry, voltage and frequency deviations, etc)
  • Active and passive harmonic filters
  • Interconnection of Renewable Energy Sources (RES) with the grid
  • Control of RES integration in the grid through power electronic converters
  • Transient phenomena caused by the operation of RES in the grid


He has supervised three Ph.D dissertations that have been completed successfully and he is currently supervising two more. He also participated and participates as member of the advisory and examination committee of numerous Ph.D dissertations.

He has participated in more than ten research projects while in three of them he was the coordinator. He also acted as evaluator of more than 20 research proposals for the European Commission (EC) and as long-term reviewer in six EC funded projects.

He is also reviewer with more than 15 scientific journals.

He is a member of Hellenic Chamber of Engineers and IEEE (Senior Member).
