Dual-source power conversion module for reliable backup supply
This technology describes a power conversion circuit that draws from two energy sources connected in series — for example, two batteries — and intelligently routes power to a load depending on whether each source is performing normally. When the primary source is healthy, a boost converter steps up its voltage to drive the output. When the primary source falters or fails, the circuit automatically switches to a buck-boost configuration that draws from the secondary source and reverses polarity as needed to maintain stable output. The result is a power supply that stays operational and regulated even as individual energy sources degrade or fail.
What you could build
A redundant power supply module for UPS systems, telecommunications equipment, or industrial controls that seamlessly maintains regulated DC output across two batteries or energy sources of varying health — sold to power electronics OEMs and industrial equipment manufacturers.
Who in Virginia should care
Defense and government contractors in Northern Virginia and the Hampton Roads corridor with needs for reliable backup power in mission-critical equipment, as well as data center operators in the Ashburn corridor.
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.
