Empirical Based Vector Inversion Generator Model

IS4S uses standardized Vector Inversion Generator (VIG) fabrication methods and spark gap switch designs to build a variety of VIG-based pulsed power devices. Testing data collected from past VIG devices is applied to a deconvoluted VIG computer model which calculates time-based voltage, current, and frequency performance for the VIG based pulsed generator. The spark gaps used in the VIG pulser’s design are included in the VIG computer model as discrete electrical parameters based on testing data. The electrical parameters of the spark gaps are translated to the spark gap’s physical parameters using Jane Lehr’s published work [1] on ultrafast spark gap switching. The discrete electrical parameters for the load and output transition geometry are layered onto the VIG-based device computer model. Desired output electrical characteristics, such as peak rise time and output voltage, can be designed by using this complete model of a VIG-based pulsed power device. The discrete electrical parameters for the represented components in the model are used to determine the physical dimensions for building the VIG and other components, such as the output transition. The model will become more predictive as the database for VIG performance data grows, allowing for trendline characterization of the deconvoluted VIG electrical and physical parameters.
