Innovative solution for electric vehicle charging - our PhD Student recognized at IECON 2024 | Gdańsk University of Technology

On November 5, 2024, during the 50th Annual Conference of the IEEE Industrial Electronics Society (IECON 2024), Mykola Lukianov, doctoral student at Gdańsk University of Technology, scientifically affiliated with the Faculty of Electronics, Telecomunications and Informatics, being under the supervision of prof. dr hab. inż. Ryszard Strzelecki and dr hab. inż. Mikołaj Bartłomiejczyk presented a project titled “Multi Active Bridge converter with DPS modulation for bidirectional EV charging from DC traction grid.” His work was recognized as the best conference presentation.

In his presentation, the doctoral student drew attention to the problem of insufficient electric vehicle charging infrastructure in cities. He pointed out that the high cost of installing charging stations is one of the main obstacles to the development of electromobility. The proposed solution involves using a new converter that enables the connection of multiple chargers to an existing DC traction network. This approach reduces the number of required components, which in turn lowers the overall costs.

A key element of the project is the use of DPS modulation, which allows for an average reduction in transformer currents by 5.7%. This leads to more efficient charging of electric vehicles. Importantly, the converter allows for independent control of individual ports, simplifying the management of the charging system.

Research conducted by our doctoral student confirmed that with DC grid input voltages of 400–800V, battery port voltages of 1000–1400V, and with port configurations rated at 3×50 kW, the proposed solution significantly improves the system’s efficiency. 

We congratulate our PhD student and wish him continued success in developing innovative technologies for electromobility!
