US Patent:

7312412, Dec 25, 2007

Filed:

Jun 17, 2004

Appl. No.:

10/870381

Inventors:

William Ray Cravey - Albuquerque NM, US
Randy D. Curry - Columbia MO, US
Kenneth Fox McDonald - Columbia MO, US
Glenn A. Anderson - St. Charles MO, US

Assignee:

Alpha-Omega Power Technologies - Albuquerque NM
The Curators of the University of Missouri - Columbia MO
The Boeing Company - Chicago IL

International Classification:

H01H 35/24
H01H 33/00
B02B 1/24

US Classification:

200 81R, 218 91, 307112

Abstract:

Method and apparatus for switching high power at high repetition rates. The apparatus is preferably a switch utilizing a pressurized flowing dielectric. The pressurized dielectric suppresses growth of dielectric breakdown byproducts, such as large bubbles and breakdown contamination, enabling lower dielectric flow rates to remove the byproducts. In addition to the advantage of lower flow rates, and thus smaller and lighter pumping means, the switch can switch high energies (up to megajoules) at fast repetition rates, up to thousands of pulses per second.

Abstract:

Method and apparatus for switching high power at high repetition rates. The apparatus is preferably a switch utilizing a pressurized flowing dielectric. The pressurized dielectric suppresses growth of dielectric breakdown byproducts, such as large bubbles and breakdown contamination, enabling lower dielectric flow rates to remove the byproducts. In addition to the advantage of lower flow rates, and thus smaller and lighter pumping means, the switch can switch high energies (up to megajoules) at fast repetition rates, up to thousands of pulses per second. The switch is preferably triggered to reduce jitter. The switch can also be used to remove water from oil.
