Highly Efficient Vector Inversion Generators

Radiance Technologies, Inc.

Huntsville, AL


Project developed a new class of fast, high-voltage pulse generators. These devices are the most compact high-voltage generators possible and have many uses in advanced propulsion systems, flash X-ray systems, and impulse radar.

This new class of devices can take electrostatically stored energy and convert it into a fast, high-voltage pulse in a one-step dynamic process on the nanosecond time scale. The devices are highly efficient and can be constructed of simple inexpensive components. They combine the functions of energy storage and voltage conversion into one simple easily manufactured unit.

Compact Vector Inversion Generator Producing 277 kV Maximum Voltage
  • Radiance has successfully demonstrated Vector Inversion Generators operating up to 500 kV in an oil bath. Scaling laws, design equations, and theoretical descriptions are complete and verified experimentally. Sizes have ranged from 2 inches in dia. up to 10 inches in dia. Devices greater than 90% efficient have been built. Several generators have been sold to other gov't agencies.
  • These devices are highly developed and can be designed for specific applications. Specific devices for impulse radar, RF weapons, and X-ray systems are being tested.
  • These devices are known as Vector Inversion Generators (VIGs)
  • Gov't markets are primarily the Army and Navy. The Navy has purchased several units for evaluation
  • One patent entitled "Apparatus System and Method for Generating High Voltages" has been submitted
  • Product is primarily being marketed to Government agencies for highly specialized applications
  • There are no remaining technological barriers hindering development of commercial applications
  • The U.S. Army has funded a Phase II SBIR for the development of the VIGs for military applications. All of the advanced development of this technology was done with these funds.
  • For NASA, the technology is capable of applications to advanced propulsion.
  • Any technological issues impeding NASA applications will be application specific.
