Portable Nanosecond Electrical Pulser

To address the Air Force need for an innovative, portable, tunable, high-voltage, nanosecond electrical pulse generator that can deliver 100 kV-300 kV to a 200 Ohm load, Intellisense Systems, Inc. (ISI) proposes to develop a Portable Nanosecond Electrical Pulser (PONSEP) device based on a new toroid high-voltage energy transfer design. Specifically, the innovation in high-voltage delivery and fast rise-time repetitive electrical pulse components will enable the PONSEP to generate nanosecond electrical pulses at the desired repetition and energy. As a result, this device offers adjustable high-voltage electrical pulse capability in the 100 kV-300 kV range in 10 kV increments, adjustable pulse width with 1000 ns steps, and pulse repetition frequency with 0.1 Hz to 0.003 Hz adjustability. In Phase I, ISI demonstrated the feasibility of the portable nanosecond pulser by developing a working breadboard for use in a laboratory setting that meets the basic requirements for repeated nanosecond electrical pulse generation. In Phase II, ISI plans to develop a laboratory-use prototype for output validation. A biologically relevant load for high-voltage delivery will be used. The prototype will address the general requirements listed above, as well as the method for electrical delivery control when transferring energy to the target.
