One of the most distinguished participants of the International Technical Fair (Hall 1, stand 1306) – H-Bridges, a team of students of the Faculty of Electronic Engineering but also the other Faculties of the University in Belgrade, has placed in the pre-fair period in the finals of the world’s largest university competition in energy electronics (International Future Energy Challenge – IFEC). The team has already won this competition in 2005 and 2019, and in 2020 has won second place.

The theme of this year’s project is the development of a micro-grid solar invertor for installation of a solar system on an electricity grid. The project is the development of a device that will adapt the energy produced on solar panels to the conditions of connection to the electricity grid. Therefore, such projects will be in the focus of the public in the future, because they enable a gradual transition to renewable energy sources in households. According to the requirements of the competition, the team managed to develop a device that meets all the requirements: galvanic isolation (provides safety in use for both the user and the device in case of failure), compactness and controllability via a smart device (end user has the ability to monitor the status of the entire device), and the efficiency of the whole system of over 95%. The modularity of this solution provides the end user with the ability to connect more of the same devices to achieve more installed power.

This year, the final round of the competition will be held at the end of July 2022 in Knoxville, Tennessee.
