Bidirectional DC-DC converter that absorbs parasitic
This technology is a DC-to-DC power converter that efficiently steps voltage up or down while handling a common real-world engineering nuisance: parasitic electrical effects from component packaging that normally waste energy or cause instability. It uses two sets of switches, two inductors, and two capacitor packages arranged so that the stray capacitances inherent in physical components are absorbed into the circuit's operation rather than fighting against it. The design also works bidirectionally, meaning power can flow either direction between source and load, which is critical for applications like battery charging and discharging. The dielectric isolation provided by the capacitor arrangement adds a safety and noise-reduction benefit useful in sensitive or high-voltage systems.
What you could build
A high-efficiency bidirectional DC-DC converter module for electric vehicle on-board chargers, battery energy storage systems, or industrial power supplies; target buyers are EV powertrain tier-1 suppliers, battery management system OEMs, and data center power infrastructure vendors.
Who in Virginia should care
Defense and aerospace contractors in Northern Virginia and Hampton Roads (e.g., shipboard and ground vehicle power systems programs) and data center operators in Loudoun County's corridor would have direct interest in efficient, isolated DC-DC conversion.
Readiness: Concept
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.
