Abstract
An energiser for an electric fence. The energiser includes, at least, one energy storage capacitor (), a charging circuit () to enable the or each storage capacitor () to be charged from an energy source (), semiconductor switching means (), and control circuit means () to facilitate controlled turning -on and -off of the semiconductor switching means () to control the duration of the discharge from the energy storage means (). In one form of the energiser a first semi-conductor switching means is arranged to connect in parallel the energy storage capacitors () to be charged and second semi-conductor switching means to connect two or more of the charged energy storage capacitors () in series to create an output pulse.
