Soft-switching series resonant DC-to-DC converter module
This technology is a circuit design for converting DC power from one voltage level to another more efficiently by using a technique called soft-switching, which reduces the energy lost as heat when transistors turn on and off. The key innovation is a resonator placed in a specific location within the circuit, combined with a controller that dynamically adjusts switching timing based on the circuit's gain. This approach improves efficiency and reduces stress on components compared to conventional hard-switching converters. It is particularly relevant for high-frequency power conversion applications where thermal management and efficiency are critical.
What you could build
A high-efficiency DC-to-DC converter module for electric vehicle onboard chargers, data center power supplies, or industrial power systems; bought by power electronics OEMs and system integrators needing compact, thermally manageable conversion stages.
Who in Virginia should care
Defense contractors and data center operators with large Virginia footprints, such as those in Northern Virginia's cloud infrastructure corridor, routinely source efficient DC-DC power conversion components.
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.
