Abstract :
Eagle Harbor Technologies, Inc. (EHT) is developing a high voltage nanosecond pulser capable of generating non-equilibrium plasmas, including dielectric barrier discharges, pseudospark discharges, and liquid plasma discharges for plasma medicine, material science, enhanced combustion, drag reduction, and other research applications. EHT nanosecond pulsers are capable of producing high voltage (up to 60 kV) pulses (width 20 - 500 ns) with fast rise times (<; 10 ns) at high pulse repetition frequency (adjustable up to 100 kHz) for continuous operation. The pulser does not require the use of saturable core magnetics, which allows for the output voltage, pulse width, and pulse repetition frequency to be independently adjustable, enabling researchers to explore non-equilibrium plasmas over a wide range of parameters. A magnetic compression stage can be added to improve the rise time and drive lower impedance loads without sacrificing high pulse repetition frequency operation.
