Research

Our group develops power electronic converters and systems spanning medium-voltage grid applications to electrified transportation — combining new circuit topologies, advanced control, and experimentally validated hardware prototypes.

Transportation Electrification

We develop power electronics for electric vehicles and charging infrastructure, including integrated onboard chargers that reuse the traction drive, bidirectional three-phase AC chargers with buck-boost capability, and resonance-based wireless power transfer systems. Our goal is charging hardware that is lighter, cheaper, and more efficient, accelerating the adoption of electrified transport.

Solid-State Transformers & Medium-Voltage DC–DC Conversion

Medium-voltage DC–DC conversion is a key enabling technology for DC grids, renewable integration, and high-power charging. We research modular multilevel converter (MMC) based DC–DC topologies — including high-frequency MMCs, current-shaping MMCs, and current-fed isolated MMCs with soft switching — that achieve high step ratios and high efficiency at medium voltage.

Energy Storage Systems

Grid-scale energy storage is essential for a reliable, renewables-dominated power system. We study power electronic interfaces for battery energy storage — from converter topologies that connect storage directly at medium voltage to control strategies that deliver grid services — with an emphasis on efficiency, power density, and cost.
