Abstract
A device for charging PFLs (Pulse Forming Lines) on a time scale of a few nanoseconds. The device includes a source transmission line (STL) connected through a switch to a pulse forming transmission line. The source line is initially charged while the PFL is uncharged, and the switch is open. The impedance of the STL is larger than the impedance of the PFL. The impedance of the STL is also tapered in order to effect an energy transfer efficiency approaching 100% from the STL to the PFL. In operation when the switch is closed, energy flows from the source line to the PFL. As the energy and voltage build on the PFL, an output switch closes and delivers the energy of the PFL to the output transmission line section. The impedance of the output transmission line section is matched to the PFL impedance so that all of the energy in the PFL flows into the output section in the form of a pulse.
