Resonant DC-DC converter with quasi-trapezoidal current
This technology is a new type of power converter that uses an electronically controlled transformer to efficiently transfer energy between two circuits. Instead of relying on a conventional magnetic core transformer alone, it embeds active switching components directly into the transformer to manage how current flows. A smart controller adjusts a specific tuning parameter—called a commutation coefficient—to shape the current waveform in a way that reduces switching losses and keeps voltage output stable regardless of how much load is connected. The result is a more efficient, compact power conversion system suited for high-frequency DC-DC conversion applications.
What you could build
A high-efficiency DC-DC converter module for data center power supplies, EV onboard chargers, or solid-state transformer platforms; target buyers are power electronics OEMs, data center infrastructure vendors, and EV powertrain suppliers seeking higher efficiency and smaller form factors.
Who in Virginia should care
Defense contractors and data center operators with large Virginia footprints—such as AWS, Microsoft Azure, and Northrop Grumman—would care about compact, high-efficiency power conversion for servers and mission-critical systems.
Readiness: Lab validated
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
