Patent number: 11962304Abstract: Some embodiments of the invention include a pre-pulse switching system. The pre-pulsing switching system may include: a power source configured to provide a voltage greater than 100 V; a pre-pulse switch coupled with the power source and configured to provide a pre-pulse having a pulse width of Tpp; and a main switch coupled with the power source and configured to provide a main pulse such that an output pulse comprises a single pulse with negligible ringing. The pre-pulse may be provided to a load by closing the pre-pulse switch while the main switch is open. The main pulse may be provided to the load by closing the main switch after a delay Tdelay after the pre-pulse switch has been opened.Type: GrantFiled: March 29, 2022Date of Patent: April 16, 2024Assignee: EHT VENTURES LLCInventors: Kenneth E. Miller, James R. Prager, Ilia Slobodov, Julian F. Picard

Publication number: 20230184232Abstract: Some embodiments of the invention include a thruster system comprising a thruster and a pulsing power supply. The thruster may include a gas inlet port; a plasma jet outlet; and a first electrode. In some embodiments, the pulsing power supply may provide an electrical potential to the first electrode with a pulse repetition frequency greater than 10 kHz, a voltage greater than 5 kilovolts. In some embodiments, the pressure downstream from the thruster can be less than 10 Torr. In some embodiments, when a plasma is produced within the thruster by energizing a gas flowing into the thruster through the gas inlet port, the plasma is expelled from the thruster through the plasma jet outlet.Type: ApplicationFiled: December 22, 2022Publication date: June 15, 2023Inventors: Timothy M. Ziemba, James R. Prager, John G. Carscadden, Kenneth E. Miller, Ilia Slobodov, Julian F. Picard, Akel Hashim
