Stability analysis tool for AC/DC power converter designs
This technology provides a mathematical method for predicting whether an AC/DC power conversion system will remain stable before it is built or deployed. It works by simplifying a complex matrix analysis of the power converter's behavior into a more manageable two-element approximation, then applying a well-established engineering test called the Nyquist criterion to determine if the system will oscillate or fail. The result is a reliable way to identify dangerous operating conditions or incompatible combinations of power sources and converters at the design stage. This is essentially a diagnostic and design-validation tool for engineers working on industrial power systems.
What you could build
A software-based stability analysis tool embedded in power electronics design suites or simulation platforms, sold to industrial power system engineers and converter manufacturers who need to validate designs before deployment.
Who in Virginia should care
Defense contractors and naval facilities in Virginia (e.g., Newport News, Norfolk) operating shipboard AC/DC power systems would have strong interest in stability validation tools.
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.
