Multi-element resonant converter with built-in overcurrent
This technology is a specialized DC-to-DC power converter that uses a multi-element resonant circuit to transfer power more efficiently while protecting itself from dangerous overcurrent conditions, such as during startup or short circuits. The resonant tank circuit is designed with both a bandpass filter and a notch filter, which together shape how current flows — boosting power delivery at the operating frequency while naturally limiting runaway current at a higher frequency. This dual-filter approach reduces wasted energy from circulating currents and heat losses. A key practical benefit is that multiple magnetic components can be consolidated into a single physical part, shrinking size and cost.
What you could build
A compact, efficient DC/DC converter module for industrial power supplies, server power systems, or EV onboard chargers, sold to power electronics OEMs and system integrators who need high-efficiency conversion with inherent fault protection.
Who in Virginia should care
Defense electronics and data center power supply manufacturers in Northern Virginia or the Hampton Roads corridor would have direct interest in compact, high-efficiency converter designs.
Readiness: Prototype likely
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.
