Multi-resonant switched-capacitor DC-DC converter
This technology is a new circuit design for power converters that use capacitors and switches to step voltages up or down efficiently. By engineering the circuit to operate at multiple resonant frequencies rather than just one, the converter can handle a wider range of operating conditions while reducing energy losses from switching. The design includes a specific arrangement of switches, diodes, and a resonant tank circuit that can be tuned to different frequency modes. It is particularly useful for high voltage conversion ratio applications, such as converting between very different voltage levels in compact electronics.
What you could build
A high-efficiency DC-DC power converter chip or module for applications like data center power supplies, electric vehicle onboard chargers, or portable electronics where wide-range voltage conversion with minimal heat loss is critical; the primary buyers would be power electronics IC manufacturers and systems integrators in automotive and computing hardware.
Who in Virginia should care
Defense contractors and data center operators in Northern Virginia, as well as power electronics suppliers serving the shipbuilding and naval sector in Hampton Roads, would have interest in efficient DC-DC conversion hardware.
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.
