Traditional silicon had a great run, but next-gen power demands a major step up.

What if you could double the independent ports of a standard H-bridge without adding a single active switch? In our latest research, we developed the X-Bridge Multiport Converter, a novel bidirectional DC-AC topology that manages multiple independent power paths for hybrid renewable energy and storage systems. Instead of relying on auxiliary DC-DC stages or extra switching legs, the X-Bridge physically restructures the converter interconnections around a central neutral node to achieve: 🔹 A 100% increase in port utilization with zero active switch penalty. 🔹 Up to a 75% reduction in active semiconductor count compared to current state-of-the-art multiport topologies. 🔹 Inherent compensation for mismatched source voltages using a modified SPWM strategy that limits semiconductor conduction intervals to just 50% of the fundamental cycle. I am looking to connect with academic and industry professionals working on power electronics, grid integration, and renewable energy storage. If you are exploring multiport converter architectures, fault-tolerant topologies, or multi-source integration, I’d love to connect and discuss potential collaborations.

Solid-state transformers have long been seen as a promising technology—but bringing them to high-voltage applications remains a significant engineering challenge. The EU-funded SSTAR project has taken an important step by validating high-voltage SST technologies designed for renewable-rich power systems, industrial microgrids, offshore energy, and data centres. The project demonstrated several key innovations, including a high-voltage SST module, a decentralised control architecture, and a bio-based dielectric fluid, while validating operation under conditions representative of future high-voltage networks. While conventional transformers will continue to play a central role in power systems for many years, projects like SSTAR show how power electronics could complement traditional technologies in applications where greater flexibility, digital control, and bidirectional power flow are becoming increasingly important. https://lnkd.in/dyWbafy7 #Transformers #SolidStateTransformers #PowerElectronics #SmartGrid #EnergyTransition

Perovskite–Silicon Tandem Solar Cells: A New Path Toward Higher Photovoltaic Efficiency Perovskite-silicon tandem solar cells are rapidly emerging as one of the most promising technologies for the next generation of high-efficiency photovoltaics. By combining a wide-bandgap perovskite top cell with a silicon bottom cell, tandem devices can utilize the solar spectrum more effectively than conventional single-junction silicon cells. Recent advances in bandgap engineering, defect passivation, interface engineering, optical management, and advanced silicon architectures have pushed tandem efficiency to remarkable levels. In 2026, a certified efficiency of 35.5% was reported for a two-terminal perovskite–silicon tandem solar cell. 🔬 In the following slides, I highlight the structure, working principle, key research challenges, major innovations, and recent efficiency milestones of this rapidly developing technology. #Perovskite #PerovskiteSolarCells #TandemSolarCells #SiliconSolarCells #Photovoltaics #SolarEnergy #RenewableEnergy #CleanEnergy #SolarTechnology #MaterialsScience #EnergyResearch #SustainableEnergy
