GaN Power Electronics
High-speed switching, device losses, parasitics, gate driving, switching transients, and the practical limits of GaN-based conversion.
Current Research
High-frequency GaN power conversion.
My current research explores how wide-bandgap semiconductor devices, high-frequency switching, advanced converter topologies, and high-frequency magnetics can be combined to create compact, efficient, and reliable power-conversion systems.
Primary PhD Direction
High-Frequency Isolated GaN-Based DC–DC Converters for Spaceborne Power Conditioning
One of my current research directions investigates high-frequency GaN-based isolated DC–DC converters for spaceborne electronic power conditioning. The broader system concept involves conversion from an approximately 70-V satellite DC bus through a pre-regulation stage to a higher-voltage DC link, followed by high-frequency isolated power conversion.
The work involves topology selection, switching-loss analysis, high-frequency transformer design, GaN device behaviour, gate-driver design, soft switching, parasitic effects, thermal management, control, electromagnetic compatibility, and reliability.

Previous Research
Intelligent battery systems.
Before moving deeper into high-frequency power conversion, my M.Tech research focused on intelligent estimation of lithium-ion battery states.
M.Tech Thesis
Deep Learning Architectures for Precise SoC and SoH Estimation in Lithium-Ion Batteries using Bio-Inspired Optimization
The work investigated deep-learning architectures including LSTM, GRU, and CNN-LSTM for State-of-Charge and State-of-Health estimation, together with bio-inspired optimisation techniques. This research provided a foundation in battery modelling, machine learning, optimisation, BMS, and data-driven engineering.
Engineering Approach
From simulation to physical reality.
I am particularly interested in the gap between an ideal mathematical model and the behaviour of a real power converter.
Model
Start with topology, equations, operating modes, device models, and analytical understanding.
Simulate
Investigate switching behaviour, stresses, losses, control response, efficiency, and operating limits.
Validate
Account for parasitics, magnetics, gate drivers, thermal behaviour, measurement limitations, and experimental results.
Beyond Engineering
Chess has shaped how I think.
I am a FIDE-rated chess player and coach. Chess has taught me to evaluate positions, distinguish short-term tactics from long-term strategy, work with incomplete information, and remain patient when the correct answer is not immediately visible.
