A novel three stage, transformer coupled L-C generator operating at 30 kV maxim output voltage has been built and tested. This type of generator has been studied by several authors and offers advantages over conventional Marx and L-C inversion generators in that only one closing switch is needed for erection, independent of the number of generator stages. Previous investigations have also shown that the proper operation of the generator is determined, primarily, by the transformer coupling coefficient and, secondly, by the value of the load. The Thevenin output inpedance is derived in this investigation for the "n" stage generator and verified through computer simulation and experimental measurements. Changes in the mimum pulse generator output are reported for several values of resistive and capacitive loads. The output pulse risetime can be significantly increased by including an output (or, "sharpening") spark gap. The output waveform shape can also be mde nearly unipolar by discharging the generator into low resistance loads (i.e., 50 to 75 Ω) via an output spark gap.
