摘要： A plasma generation system includes a pulse generator having at least one switch and that is configured to convert a DC voltage to a desired high frequency, high breakdown voltage pulse sufficient to break down a high-breakdown voltage gap, wherein all pulse generator switches are solely low to medium voltage, high frequency switches, and further configured to apply the breakdown voltage to a plasma load for the generation of plasma. In one application, the plasma generation system is useful to manipulate the flow of jets and provide highly efficient acoustic noise reduction.

摘要： A gas turbine combustion system passive air-fuel mixing prechamber includes one or more fuel passages. Each fuel passage includes at least one downstream fuel injection orifice. One or more fluid conduits connect an upstream portion of at least one fuel passage with one or more air passages such that pressure drops across each fuel injection orifice substantially self-equalize in a passive manner with corresponding air passage pressure drops over a broad range of fuel lower heating value (LHV) from about 150 Btu/scf to about 900 Btu/scf of fuel passing through the fuel passage while mixing with air passing through one or more connected fluid conduits. The effective area of each fluid conduit relative to the corresponding fuel and air passages is dependent upon the desired fuel LHV operating range.

摘要： A high voltage, high speed, and high repetition rate pulse generator solves the high pulse repetition rate limitations associated with RF power amplifiers. The pulse generator employs resonant techniques to provide current limiting features that allow for continued high voltage, high speed, and high repetition pulse rate operation of the pulse generator without impairment of the pulse generator during both short circuit and open circuit load conditions.

摘要： A high-frequency, high-voltage electron switch includes an electron source, a steering mechanism, a mask or anode plate, and a target. The electron source produces a beam of electrons with a voltage of at least about 1 kV that impinges upon the anode plate. The steering mechanism scans the electron beam across the anode plate at a scanning frequency of at least about 10 MHz. A hole or aperture is provided in the anode plate that allows the electron beam to pass through and produce a pulsed, high-voltage current in the target with a very high-frequency repetition rate and a very fast rise time. The pulsed, high-voltage current produced in the target can be used to cause a high-voltage source to turn on and off.

摘要： A simplified electronic ballast for a discharge lamp which provides dimming by control of inverter frequency through modulation of magnetizing current in a transformer such that the switching frequency is made substantially independent of the load presented. The principle of frequency control in a manner independent of the load is extendable to other types of loads and power supplies and converters to regulate power coupled to the load. Clamping capacitors are used to replace other clamping circuits in order to allow current injection to be controlled by a simple variable voltage while frequency control by current injection provides enhanced circuit performance.
