Abstract:
1. A bipolar pulse generator, comprising: a voltage charged first transmission line circuit; a voltage opposite polarity charged second transmission line circuit; a load coupled to series connect the first and the second transmission line circuits at the distal end; and a closing switch switchably coupled to the first transmission line circuit at a near end that generates a bipolar pulse across the load based on the charge in each of the transmission line circuits, wherein: the first transmission line circuit comprises a sequentially stepped, voltage charged two conductor transmission line circuit having at least two steps; the second transmission line circuit comprises a two conductor transmission line circuit, wherein the last step of the first transmission line circuit forms an equally charged one of the conductors of the second transmission line circuit and the center conductor of a three-conductor transmission line circuit that combines the first and the second transmission line circuits; the load is positioned between outer conductors of the three conductor transmission line at their distal end; and the sequentially stepped, voltage charged two-conductor transmission line circuit includes one conductor that is switchably coupled to a common transmission line conductor at the near end that is shared with the three conductor transmission line circuit and the second transmission line circuit.
