Patent number: 7390984Abstract: 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.Type: GrantFiled: June 13, 2006Date of Patent: June 24, 2008Assignees: Alpha-Omega Power Technologies Ltd. Co., The Curators of the University of Missouri, The Boeing CompanyInventors: William Ray Cravey, Randy D. Curry, Kenneth Fox McDonald, Glenn A. Anderson, Richard Sears

Patent number: 6362604Abstract: An apparatus and method for generating slow rise-time, high voltage electrical pulses to a load, preferably using an existing transformer/rectifier set or power supply to charge an inversion or high voltage switching circuit to produce the pulsed voltage. An energy recovery circuit (100, 102) is used to return unused energy from the load (24) back to the means for producing pulsed voltage (110, 130). A load matching circuit (120) uses a blocking diode and a capacitor for charging the load. An additional blocking diode (32) inhibits load voltage discharge back through the slow pulse generating circuit. A transformer (20) can be used to step-up voltage from the inversion circuit, or high voltage switching circuit, to the load. One or more magnetic switch stages are used to transfer energy from the inversion circuit, or high voltage switching circuit, to the load matching circuit. A fire-on voltage controller (66) triggers the inversion or high voltage switching circuit.Type: GrantFiled: September 28, 1999Date of Patent: March 26, 2002Assignee: Alpha-Omega Power Technologies, L.L.C.Inventor: William Ray Cravey
