Ellis Power Group
Power Electronics

Electrical energy conversion quietly underpins nearly every modern technology. We develop the power-electronics technologies that enable a more efficient and electrified future.

Our Research Join the Group

About the Group

Our group develops advanced power-conversion architectures and circuit techniques that enable more efficient, compact, and capable systems for applications including data-center power delivery, space systems, renewable energy integration, electric transportation, biomedical devices, and next-generation computing platforms. Research topics span converter design, topology development, control, modeling, soft-switching techniques, optimization, and advanced packaging.

We are a strongly hardware-focused lab composed of students and researchers passionate about advancing the state-of-the-art in power electronics. Most projects culminate in high-performance prototypes, providing students with extensive hands-on experience in rapid hardware development, testing, and experimental validation. To learn more about our current research directions and both past and ongoing projects, please visit our Research page.
