Generation of high voltage nanosecond pulses using Pulse Sharpening switch

The paper exhibits the simulation and experimental results of Pulse sharpening switch along with a 250 kV High Voltage Pulse Transformer for generation of high voltage fast risetime short duration pulse. The Pulse transformer is employed to charge the Pulse forming line integrated with Pulse sharpening switch. The Pulse sharpening switch is a two electrode fast spark gap switch. Fast risetime short duration pulse depends upon the fast closure of Pulse sharpening switch. The switch is pressurized at 3.5 bar with sulphur hexafluoride insulating gas and the inter electrode gap of the Pulse sharpening switch is 2mm. The closure of the Pulse sharpening switch delivers the output voltage of 125 kV, 1 nanosecond rise time with 70 ohm load.
