Current-balancing power stage for paralleled transistor arrays
This technology is a circuit design that solves a common problem when connecting multiple power transistors in parallel to handle large currents. When transistors are wired in parallel, small differences in their characteristics cause one to carry more current than the others, which stresses that device and can cause failures. This design adds small resistive elements at specific points in the circuit to automatically force the transistors to share the load more evenly without complex external control logic. The result is a more reliable, thermally balanced power circuit that can be built with standard components.
What you could build
A drop-in power stage design for motor drives, EV inverters, or industrial power supplies where multiple transistors must be paralleled to handle high current loads; target buyers are power electronics module manufacturers and automotive Tier 1 suppliers designing traction inverters or onboard chargers.
Who in Virginia should care
Defense and government electronics contractors in Northern Virginia, or power electronics suppliers supporting shipbuilding and naval systems at Newport News, would have direct use for robust high-current switching designs.
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.
