Abstract
An electric fence energizer including an energy storage capacitor (11), a controllable switch (17) for controlling the charge in the storage capacitor, a control circuit (15) connected to the controllable switch, and a sensor (19,20) that can relay information to the control circuit regarding the perceived electrical load on the output of the electric fence energizer. The control circuit upon receipt of the information from the sensor operates the controllable switch so that the charge on the capacitor varies so as to allow a continuously varying range of output voltages on the electric fence line once the capacitor is discharged.
