1. A circuit for an electric pulse generator suitable for use in an electric fence energizer, capable from time to time of generating or constructing one or more substantially unipolar pulses of power having a controlled shape, comprising a control means capable of initiating and controlling the generation of a pulse, a shaping means capable of determining the shape of the pulse when generated at a first low voltage, wherein the amplitude of the pulse has a rising phase in which it rises from a base level up to a peak amplitude gradually at first, then more rapidly, then slows to a rounded peak, then falls in a falling phase which is substantially a mirror image of the rising phase, so that a smooth and substantially symmetrical pulse outline is generated;

  • and a pulse transforming means to transform the pulse so generated into a pulse at a second, generally higher voltage without substantial alteration to the shape of the initially generated pulse.
