Trapezoidal current control for stable modular DC-DC
This technology describes a smarter way to control power flow inside a type of compact, high-efficiency power converter that replaces bulky magnetic transformers with a circuit-based equivalent. The key innovation is a control method called trapezoidal current modulation, which shapes the electrical current waveform using a tunable parameter to keep voltage output stable regardless of how much load is connected. By adjusting this single parameter between defined limits, the controller can optimize efficiency and share current evenly across parallel converter modules. The result is a power converter that is more adaptable, easier to scale, and better suited for situations where load conditions vary widely.
What you could build
A high-density DC-DC power converter module targeting data center power distribution or electric vehicle onboard chargers, sold to power electronics OEMs or hyperscale data center operators seeking compact, efficient alternatives to magnetic-transformer-based designs.
Who in Virginia should care
Northern Virginia data center operators and defense electronics contractors with power conversion supply chain interests would be logical targets.
Readiness: Lab validated
