Who are We?
H-Bridges team is a group of hard-working and enthusiastic students at the University of Belgrade, Serbia eager to gain theoretical and practical knowledge in the field of power electronics. The team is established with the aim to compete in the International Future Energy Challenge organised by the largest technical organisation IEEE (Institute of Electrical and Electronics Engineer). The team consists of four sub teams:
- Fundraising and Marketing
where the first three teams represent the core of research and development. The fundraising and marketing team has the difficult task of gathering public attention and directing the companies to invest in our team. The specifications of the competition are such that the funding must arrive from the proactive approach of the students working in the FR team. The expenditure of the team is extensive. The cost of the electronic components, PCBs, testing equipment, as well as travel expenses to the semifinals and finals of the competition must be covered.
Smart, efficient, and light solar microgrid inverter with the rated power of 1 kW is the topic of this year’s IFEC competition. This project aligns with the industry’s aim to achieve highly efficient system that has a task of converting solar to electrical energy to power the consumers of the microgrid or connect to a distribution system. Specifications are given by the IFEC and, among other, include:
- Variable input voltage 30-60V
- Grid output voltage, 50-60Hz
- Efficiency over 95%
- Galvanic isolation
Our goal is to design and model robust hardware and implement state-of-the-art software to achieve the best solution for the problem at hand. This is done in our Laboratory for Electrical Drives at School of Electrical Engineering, University of Belgrade, where the team is stationed.
H-Bridges and Eurocircuits
Cooperation between Eurocircuits and H-Bridges is founded because we believe that the efficiency of our prototype can be improved by implementation of innovative solutions in power electronics.
Through extensive research, we have garnered the means to include wide bandgap (WBG) devices, such as gallium nitride (GaN) and silicon carbide (SiC) based switching components, in our prototype. Design of our 1 kW system incorporates GaN transistors used in high frequency applications characterized with low power losses resulting in high efficiency of the device. The specific layout of the PCB with WBG devices must be thoroughly researched and carefully designed. The PCBs of high quality and fast delivery time that Eurocircuits has provided is the basis of our testing process. With them, the results of the advance will be noticeable.
Eurocircuits and our team join forces for better utilisation of the electronic devices in renewable energy sources. Shaping a more sustainable world of the future is of great importance to all of us!
