Hybrid-modulation inverter for lower switching losses

Energy & Power ElectronicsElectronics & SemiconductorsLab validated

This technology improves how DC power is converted to AC power by using a smarter switching strategy in power converters. Instead of applying a single control method throughout the entire conversion cycle, it divides each half-cycle into distinct regions and applies the best-suited switching technique in each region. This hybrid approach lets engineers optimize for efficiency, heat management, or output quality in ways that a single fixed method cannot achieve. The result is a resonant converter that can be tuned to perform better across different operating conditions.

What you could build

A higher-efficiency inverter module for EV chargers, solar inverters, or industrial power supplies where switching losses and thermal management are critical cost and reliability factors; buyers would be power electronics OEMs and tier-1 EV charging equipment manufacturers.

Who in Virginia should care

Defense contractors and naval shipboard power system integrators in the Hampton Roads and Northern Virginia corridors, plus data center UPS and power infrastructure suppliers, would have interest in more efficient DC-to-AC conversion.

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.
