Portfolio

This project is a robot which is controlled by software written on a PC, based on images received from the webcam. It can also be controlled by simple vocal commands or directly by keyboard.

Image analysis robot

This project consists of an interface used between hardware equipment and a NI board. The whole project has the purpose to test potentiometers and rotary encoders.

Hardware interface

This project consists of a small robot used for sumo competitions, having weight limitations of 500g and dimensional limitations of 10x10cm.

Sumo robot

This converter prototype was used for research purpose and it has a novel circuit topology.

Bi-Directional Hybrid DC-DC Converter With Large Conversion Ratio for Microgrid DC Busses Interface

IEEE Transactions

This paper proposes a bi-directional DC-DC converter used as interface between the battery stack and the DC bus in a microgrid application, highlighting its main feature that permits a large conversion rate, with a low number of semiconductors and without using transformers. Analytical descriptions, design aspects, digital simulation and preliminary experimental results are presented, in order to check its operation in both power flow modes, emphasizing the transition between step-up and step-down regimes.
