On October 24, 2025, Riga Technical University (RTU) hosted the 66th International Scientific Conference on Power and Electrical Engineering (RTUCON2025), an international forum that brought together researchers, engineers, industry representatives and doctoral students from around the world to discuss recent advances in power and electrical engineering.
The conference took place at the Domus Auditorialis auditorium center of RTU and featured a full‑day programme combining virtual and in‑person sessions, including keynote lectures, oral presentations, poster sessions and networking activities. The programme covered a wide range of topics such as Power Electronics, Smart Grids, Power and Energy Systems, Electrical Machines, ICT in Electrical Engineering and Engineering Education.
As an ENHANCE partner, Riga Technical University actively contributed to the scientific programme of RTUCON2025 through poster and oral presentations addressing key topics in energy storage and power conversion. Members of the RTU–ENHANCE team presented the poster “Modelling of PV‑Fed DC Microgrid with Hybrid Energy Storage to Simulate Long‑Term Operations”, authored by Ģirts Staņa and Kaspars Kroics. In addition, Kaspars Kroics delivered two oral presentations in the field of power electronics: “An Interleaved Double Dual Buck‑Boost Converter with a Low‑Loss Modulation Strategy”, and, co‑authored with Kristiāns Gaspersons, “Comparison of Different Approaches to Obtain High Voltage Gain with Interleaved Modular GaN Transistor‑Based DC‑DC Converters”.
Together, these contributions showcase research directions closely aligned with the objectives of the ENHANCE Europe project, particularly in relation to photovoltaic integration, hybrid energy storage and high‑efficiency power conversion technologies, which are relevant for applications such as asphalt solar collectors integrated into road infrastructure.
One of the highlights of the conference was the keynote lecture delivered by Dr. Andrii Chub (Tallinn University of Technology), entitled “Partial Power Converters for High‑Efficiency DC Microgrids”. The talk addressed the growing relevance of DC microgrids in the context of the global energy transition and presented partial power converters as a promising approach to achieve higher efficiency, reduced losses and improved power density in renewable‑based energy systems. The keynote explored architectural trade‑offs, control challenges and emerging converter topologies, offering valuable insights for future resilient and sustainable DC systems.
Through its engagement in events such as RTUCON2025, ENHANCE continues to support international collaboration, knowledge exchange and research excellence in strategic engineering fields, strengthening connections between partner universities and the global scientific community.
