Next Generation Inverter Technologies

A new inverter / converter concept is proposed which combines the next generation of semiconductor switching technology with two sided microchannel cooling and a new folded planar topology is proposed. It results in the combined improvement of all the three key performance parameters: specific power ,efficiency and reliability. Furthermore its distributed architecture facilitates integration with various distributed loads such as linear and rotary electromechanical systems.

The applications which will benefit the most from this development are those where specific weight, efficiency and reliability are key. They include aviation propulsion in both the hub and the rim motors for integrated motor fan systems; flight control actuators; linear systems such as cargo movers; high specific motors for inertial wheel for satellite, winches for both aero systems and tethers; low speed robotics; distributed systems for de-icing.

The major thrust in commercial all-electric aviation critically depends on propulsion system with high specific power efficiency and reliability. This inverter development will provide a major enhancement to electric propulsion such as the Polarix turn-less ACTS motor whose key attribute is its High specific power, efficiency and reliability.

This is early/mid-stage (TRL 6) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
