I-squared average current mode controller for fast DC-DC
This technology improves how switching power converters — the circuits that regulate voltage and current in electronics — respond to sudden changes in load or input conditions. It adds a fast, direct feedback path from a current sensor to the converter's control modulator, alongside a slower integrating path that tracks average current. The result is a power controller that reacts quickly to disturbances without becoming unstable, while still maintaining the precise average-current regulation that protects components and ensures efficiency. Voltage output can also be folded into the slower path to keep the overall system well-behaved.
What you could build
A controller IC or embedded control module for DC-DC power converters used in power supplies, motor drives, or fast-charging systems; buyers would be power semiconductor companies, power supply OEMs, and EV or data center power management firms.
Who in Virginia should care
Defense electronics contractors and data center operators in Northern Virginia with stringent power supply efficiency and dynamic response requirements would have 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.
