  • Publication number: 20090139844
    Abstract: A dielectric insulated mechanical switch is coupled to a capacitive energy storage arrangement and a pulse forming network. The dielectric insulated mechanical switch is immersed in a dielectric substance. A controller is coupled to the dielectric insulated mechanical switch. The controller is programmed to selectively open and close the dielectric insulated mechanical switch so as to supply energy stored in the capacitive energy storage device to the pulse forming network and thereby form a high voltage energy pulse.
    Type: Application

  • Patent number: 7485989
    Abstract: A system for generating a high voltage energy pulse comprises a capacitive energy storage arrangement that is coupled to a direct current (DC) power supply. The capacitive energy storage arrangement stores energy from the power supply. The system also includes a pulse forming network for forming frequency contents of a high voltage energy pulse. A dielectric insulated mechanical switch is coupled to the capacitive energy storage arrangement and the pulse forming network. The dielectric insulated mechanical switch is immersed in a dielectric substance. A controller is coupled to the dielectric insulated mechanical switch. The controller is programmed to selectively open and close the dielectric insulated mechanical switch so as to supply energy stored in the capacitive energy storage device to the pulse forming network and thereby form the high voltage energy pulse.
