Fault-tolerant multi-three-phase drive with isolated DC buses
This technology is a smarter way to control large electric motors that use multiple sets of windings — a design common in high-power industrial and vehicle applications. It splits the DC power supply into two halves (upper and lower) and distributes groups of inverters across each half, rather than running everything off a single shared bus. This balances the electrical load more evenly, reduces stress on individual components, and allows the system to handle higher total power without scaling up each individual part. The result is a more efficient, fault-tolerant motor drive architecture suited for demanding, high-power environments.
What you could build
A drop-in drive architecture for high-power electric motors used in industrial machinery, marine propulsion, or electric aircraft — sold to motor drive OEMs or integrated into propulsion platforms by defense and aerospace primes who need fault tolerance and high power density.
Who in Virginia should care
Defense primes and naval systems integrators in Virginia (Huntington Ingalls, Leidos, General Dynamics) working on electric ship propulsion and directed-energy power systems would be natural contacts.
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.
