Abstract: A pulse generator comprises a pulse forming line having a helical core winding surrounded by an outer winding, and a transformer having primary and secondary windings. The secondary winding is arranged about the core winding and the primary winding is arranged to co-act with the secondary winding such that the primary winding energizes the secondary winding when a suitable voltage is applied to the primary winding by a charging circuit connected to either end of the winding. The secondary winding through transformer action charges the pulse forming line. The pulse forming line has a load and a switch connected between the core winding and the outer winding. At the appropriate time the switch is closed such that energy stored in the line is discharged to the load as a pulse.

Abstract: A high voltage pulse generator for providing a high voltage pulse across a dielectric switch comprises a main high voltage pulse generator, an energy storing pulse forming line connected at one end to the main pulse generator and connected at the other end to an electrode of the dielectric switch, a high voltage trigger pulse generator and a ferrite loaded shock line. The ferrite loaded shock line, preferably located within the pulse forming line (or within a line on the output side of the switch), is connected at one end to the trigger pulse generator via a coaxial inner conductor and connected at the other end to a trigger electrode located within the dielectric switch. The pulse forming line enables a high voltage pulse to build up on the electrode of the dielectric switch, the trigger pulse having its edges sharpened by the shock line and triggering a discharge across a dielectric to an output line. This produces an extremely fast, high voltage pulse, e.g., for radar transmitter.
