Analysis of Grounding for Pulse Forming Net

High-powered pulsed powers supply for shipboard launching device in parallel, every unit can discharge hundreds of thousands of amperes current to the launching device, to satisfy the demand of launching, power units discharge in designed sequence. In order to generate hundreds of thousands of amperes current, power voltage must reach ten thousand volt. So the negative pole of power must be grounded to keep the system safe. Analysis results show that current through grounding connection will be generated when multiple points grounding is adopt, this paper calculates out the current through grounding connection by simulation, at last, this paper put forward that single point grounding is suitable for the pulse forming net system, which can eliminate the current through the grounding connection.
