Electrical Energy Management Systems (EEMS)
Research in this domain focuses on the development of sophisticated control algorithms and power conditioning interfaces tailored for a diversified energy storage portfolio. This portfolio encompasses Lithium-ion batteries, supercapacitors, and green fuels, including ammonia and hydrogen fuel cells. A primary objective of this work is the advancement of comprehensive State-of-X (SoX) estimation frameworks. By integrating high-fidelity monitoring for State-of-Charge (SoC) and State-of-Health (SoH), the research ensures optimal performance through intelligent control, contactless monitoring, and efficient energy dispatch. These innovations are critical for maintaining the longevity and reliability of next-generation energy systems.
High-Frequency (HF) Power Conversion
Our research pushes the boundaries of power distribution into the tens to hundreds of kHz range. Operating at these frequencies significantly enhances the dynamic response of the system while enabling a drastic reduction in the physical volume and weight of passive components (transformers, capacitors and inductors).
Intelligent DC Distribution & Safety
We are engineering the building blocks of the modern DC microgrid, including Solid-State Transformers , DC repeaters, and active voltage dip restorers. A primary focus is the development of high-speed DC circuit breakers and safety devices to mitigate the risks associated with DC arcing and faults.
Aerospace & Space Power Systems
This area focuses on the development of high-reliability, radiation-hardened power architectures for space applications. By utilizing both DC and HFAC distribution, we are now working on robust systems capable of operating in extreme orbital environments.
Smart Infrastructure and V2X
The intersection of power and mobility is addressed through the integration of Vehicle-to-Everything (V2X) connections, smart mobility platforms, and high-speed transit security. It is ensured by this research that the EV charging infrastructure serves as both a consumer and a contributor to grid stability. In the coming years, Vehicle-to-Grid (V2G) technology is established as a primary focus for future grid development.
Representative Research Projects:
Magnetic Power Distribution (Contactless Busbars): Utilizing high-frequency magnetics and high-permeability materials, we have developed a novel magnetic power bar for low-leakage power transfer. This solderless connection method simplifies industrial assembly and maintenance. Our research investigates high-frequency flux distribution, leakage flux mitigation, and the implementation of magnetic bypass circuits.
High-Voltage DC (HVDC) Transmission and Conversion: To enable efficient long-distance power transmission and localized distribution, we employ multilevel power conversion topologies. Our work focuses on the control and modulation of high-voltage power electronics to achieve high-efficiency conversion with minimal harmonic distortion.
Robust Space Power Architectures: The trade-offs between DC and HFAC distribution for lunar and orbital habitats are examined. Key research challenges are addressed, including the assurance of high tolerance to electromagnetic interference (EMI) and ionizing radiation. Stability is maintained across wide temperature gradients, and mission-critical levels of robustness and reliability required for extraterrestrial deployment are achieved through this research.
