Single-source hybrid multilevel inverter module
This technology is a smarter type of power inverter — the device that converts DC electricity (like from a solar panel or battery) into the AC electricity that powers homes and businesses. Instead of using a separate battery or power source for every stage of the conversion process, this design uses a mix of real DC sources and self-charging capacitors, reducing hardware cost and complexity. A sophisticated controller manages exactly when each circuit stage switches on and off, keeping the capacitors charged to the right level automatically. The result is a cleaner, more efficient AC output with more voltage 'steps' (levels) than traditional inverters, which reduces electrical noise and heat.
What you could build
A compact, high-efficiency power inverter module for solar inverters, EV charging stations, or industrial motor drives where lower hardware cost and cleaner output waveform are competitive advantages; target buyers are power electronics OEMs and renewable energy system integrators.
Who in Virginia should care
Virginia-based defense contractors, naval systems integrators, and data center power infrastructure companies that require high-efficiency DC-AC conversion would have direct interest.
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.
