Abstract
Conference Title: 2017 IEEE International Conference on Plasma Science (ICOPS) Conference Start Date: 2017, May 21 Conference End Date: 2017, May 25 Conference Location: Atlantic City, NJ, USA The Mercury pulsed power generator is an 8 MV inductive voltage adder with six induction cells. The desired current and voltage pulse shapes for each cell are approximately trapezoidal. However, during full-voltage operation, the cell insulators and anodized surfaces typically require periodic cleaning to prevent potential flashover events. Such flashovers are undesirable and may alter the pulse shape and energy delivered to the load region. We report our initial endeavor, using signal processing and pattern recognition techniques, to search for any preflashover signatures. Estimation of pulse parameters were determined using a combination of genetic algorithm and gradient descent approaches. Unwanted oscillation parameter estimation, such as energy and spectrum, were estimated using time-frequency analysis. Additionally, principal component analysis is used to form an initial approach at determining system health. We thank the Naval Research Laboratory for providing representative pulsed power waveforms for the Mercury generator.
