SKILLS

Doctoral & postdoctoral research has endowed me with the following skills:

. Modeling of motor drives, especially Indirect Vector Control Drives

(IVCD).

. Hardware Implementation of the complete motor drive.

. Design and calculations of the full armature of induction motors.

. Design of power electronics devices, such as SMPS, Inverters,

Rectifiers.

. Algorithm design, like Rotor Time Constant Estimator (RTCE), Combined

Search Controller-RTCE and Combined Loss-model Controller-RTCE.

. Simulation of IVCD with embedded estimators/controllers, both in

steady-state (MATLAB -SIMULINK) and transients (SIMNON).

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

ENGINEERING/ INDSUSTRIAL EXPERIENCE

10/1994- Consultant & Researcher, freelance .

05/2013

As a researcher was involved in several electric

machine & drives projects. The most important are

listed below:

2009-2010

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

2006-2012 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

2003 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.

2002

Funded by a municipal authority in Thessaloniki,

Greece.

My contribution included calculations, simulation,

practical

wiring aspects & communicating with the rewiring

workshop.

2001 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

2000 researcher, regarding theoretical analysis,

calculations, simulation & practical winding

aspects.

2000 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

1996-1999 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.

1994-2012

Design of an IGBT switched Voltage Fed Inverter for

motor drive applications.

2003-2004

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.

1/2004-4/200 Operational Engineer under contract of the Hellenic

6 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.

12/1992-9/19 Technical Manager in EMS Electronics, a company

94 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.

6/1992-11/19 Field Engineer in theTechnical Support Dept. of

92 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.
