High Reliability, Low EMI, Wide Bandgap Power Conversion for Air & Space Applications

About project
Project period
-

Innovation

This program continues the development of soft switching power conversion technology using wide band gap power semiconductors. Soft switching reduces component and system-level electromagnetic interference (EMI) issues regardless of the application. The soft switching control approach enables parallel operation of disparate power generation sources. It offers high reliability, rock-solid system stability when powering unruly loads including constant power and pulsed loads. This project will demonstrate soft switching in a...

Advanced High Voltage DC Generator System for Aerospace with Rapid Dynamic Response

About project
Project period
-

Innovation

Proposed generator would be an enabler of directed energy weapons (e.g. lasers), which are fundamentally more precise and less expensive to operate than their traditional counterparts.

Objectives 

This project seeks to increase power density, controllability, reliability, and manufacturability of HVDC generator systems. The four work packages detailed below focus on addressing these four technical challenges, respectively. 

  1. High-Speed HVDC Generator Rotor High-rotor speed enables high power density in generators, but presents...

Innovation

Develop thin-film lithium niobate on insulator technology for100 GHz optical modulation in telecom and DoD applications.

Objective

Electrooptic (EO) crystals, in particular lithium niobate (LN),are critically important for high-speed optical modulation. They are used in applications such as high data-rate optical fiber communications and high frequency receivers. Achieving the high modulation rates needed for fifth/sixth generation technology standards for broadband cellular networks (5G/6G) and defense applications is challenging. As a...
