Recent Work
Ultra-High-Frequency Power Conversion
Development and experimental demonstration of a 1MHz, 5kW isolated resonant converter – one of the highest-frequency, high-power converters reported to date.
Advanced Control Algorithms and AI Integration
Invention of new control methods to improve microgrid resiliency. For example, the extension of the conventional droop control algorithm to an “Extended Droop Control” for handling pulsed loads in an n-converter DC microgrid, with seamless reversion to resistive droop control when the pulses are inactive. This work, validated experimentally, enhances system stability and has been implemented in a hierarchical digital twin testbed for more complex systems.
Electrified Transportation and “Digital Shadows”
Design of a digital shadow for electric vertical takeoff and landing (eVTOL) powertrains, aimed at monitoring the remaining useful life of critical components. It is a functional framework that can track health indicators of an eVTOL’s power electronics and drive components in real time, which provides a foundation for prognostics and health management in electrified aircraft – a key to ensuring safety and reliability in emerging electric aviation.
Medium Frequency Transformer Design
Design, simulation, and development of a 1:1 800 V 20 kHz 10 kW Dual Active Bridge and its transformer, to be implemented inside a DC Microgrid in order to work on the DC Microgrid concept. Simulation and real-life testing of a DC Microgrid model where said DAB is going to be employed.
The Energy Optimization Lab is exploring the edge of technology as it relates to power and energy.
