Abstract: An electric fence energizer comprising an energy storage capacitor (2), which is able to be discharged into the primary (3) of a step-up transformer, the secondary (4) of which is connected to the electric fence, and comprising an internal electronic control device for controlling the discharge pulses from the capacitor (2) to the electric fence. The capacitor (2) is discharged into a circuit consisting, in series and in the following order, of a first electronic actuator (5), followed by the primary (3) of the transformer, followed by a second electronic actuator (6), the opening and closing of each one of the two electronic actuators (5, 6) being able to be controlled, and each one of said electronic actuators being able, during discharging, to interrupt the discharge pulses from the capacitor (2) into the primary (3) of the transformer, and then to permit said pulses.
