Presentation

Switched Mode Power Supplies(SMPS)
-Study and develop new topologies in the field of SMPS. By improving the power supply of a system one can improve the life time and the performances of the whole system.
-Develop new topologies and control methods that can improve the efficiency, reduce the costs and the size of the system. Embrace new concepts and trends that emerge in this continuous evolving domain of power electronics.
Digital Control
-Study and develop new non-linear algorithms that can be used in the field of power supplies in order to improve loadresponses and total harmonic distortions for output current in grid tied inverters.
-Develop algorithms that are not time consuming and are easy to be integrated in specialised controllers for SMPS.
System Modelling and Simulations
-Study and develop new ways on how to average switched mode power supplies in order to reduce simulation times.
-Develop macro-model from the switched mode power converters in order to improve simulation times. Develop models for the integrated circuits for simulating the power supply as accurate as possible in order to prevent possible malfunctions.
Embedded Systems
-Study and develop new ways to optimise the software algorithms that run on microcontroller, DSP and ARM.
-Develop systems with microcontrollers in C/C++ and assembly for different types of applications: low cost, time constrained, wireless, industrial and sensing.
