• Fuzzy Neural Network-FNN competency and C++ programming.

ENGINEERING/ INDSUSTRIAL EXPERIENCE

2003-2004 Consultant & Researcher, freelance .

As a researcher was involved in several electric machine & drives projects. The most important are listed below:

 Design of a transformer ageing predictor. Although the project was suspended at an early stage, the aim was to develop a simple and cost-effective estimator based on current & voltage measurements only.

The project was initially to be funded by the Secretariat of Industry, but the fiscal crisis prevented it.

 Supervision/design of various power supplies, both linear & switched, all being part of theses in the T.E.I.TH.

My contribution usually was in the power converters included in the switched power supplies. Most of the times it was around Buck/Boost & Flyback DC-DC converters.

 Redesign of a KHM 3ph, 55kW induction motor armature.

Funded by a municipal authority in Thessaloniki, Greece.

My contribution included calculations, simulation, practical wiring aspects & communicating with the rewiring workshop.

 Design of a special transformer with a tertiary “control “ winding. It was based on an AEG 3ph, 50 kW, 20/0.4 kV distribution transformer, modified along the lines of the Wanlass motor.

Joint project of AEG Hellas & the A.U.TH. Main researcher, regarding theoretical analysis, calculations, simulation & practical winding aspects.

 Partial design of special purpose Buck converter.

Helping a colleague with practical aspects of the power module (switching & rectification).

 Design of a novel induction motor, with Double In Series Winding. It was based on an ABB 3ph, 0.75 kW motor.

 Design of a special switch to implement the change from Half to Full winding mode & vice versa. It was based on a modified Y-D commutator.

Both projects were funded by the A.U.TH. & the General Secretariat of Technology. Main researcher, regarding theoretical analysis, calculations, simulation & testing.

 Design of an IGBT switched Voltage Fed Inverter for motor drive applications.

Project funded by the A.U.TH. & the General Secretariat of Technology. Main researcher, regarding theoretical analysis, calculations, simulation, actual construction & testing.

Under the capacity of consultant was mainly contracted as

 Technical Supervisor at the OLYMPIC SA (Thessaloniki, Greece). Responsible for the maintenance and upgrade of electric/electronic equipment and networks.

 Lead engineer & project manager for the complete restoration of a 20,000 sq. ft. hotel-building, in time & within budget limits (about 350k GBP). It included detailed scheduling of the reconstruction procedure, set way-points & time goals. The materiel on demand was integral part of the planning. An interdisciplinary crew of 15-25 people were at disposal.

1/2004-4/2006 Operational Engineer under contract of the Hellenic Transmission System Operator.

Main responsibility the stability control of the Greek electrical grid and component maintenance scheduling (mainly power transformers & circuit breakers).

Main achievement was the impeccable grid functioning during the Olympic games of 2004.

12/1992-9/1994

Technical Manager in EMS Electronics, a company marketing, installing and integrating telecommunication equipment.

Main responsibility the design and construction of customized ISDN networks for large customers (commercial banks, insurance companies, A.U.TH. etc). Also, was responsible for the communication with international contacts and provide technical advice to customers & to the sales manager.

6/1992-11/1992 Field Engineer in theTechnical Support Dept. of INNOVA SYSTEMS, a company marketing CAD, CAM & SIM systems for the textile industry.

Responsible for installing & servicing the complete range of automation systems the company marketed.
