Low-loss DC-DC converter module for EVs and data centers
This technology is a DC-to-DC power converter that uses at least three switching circuits connected to both a power source and a load, with all outputs wired together into a resonant circuit forming a closed loop. The resonant architecture allows energy to circulate efficiently between stages, reducing switching losses that plague conventional converters. The design can convert voltage levels between a source and a load more efficiently than standard topologies by leveraging the shared resonant tank. This is fundamentally a circuit architecture invention—the value is in how the switches and resonant elements are interconnected, not in exotic materials or new physics.
What you could build
A high-efficiency DC-DC converter module for EV onboard chargers, data center power supplies, or solar inverter stages; target buyers would be power electronics OEMs and Tier 1 automotive suppliers integrating efficient voltage conversion into their systems.
Who in Virginia should care
Defense and government contractors in Northern Virginia with power electronics needs, as well as data center operators concentrated in Loudoun County seeking efficient power conversion solutions.
