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.
Claims18
An electric fence energiser comprising an energy storage capacitor, a controllable switch arranged to control a charge in said capacitor, a control circuit connected to said controllable switch, a sensing means that can relay information to said control circuit regarding a perceived electrical load on an output of the electric fence energiser, characterized in that said control circuit upon receipt of information from said sensing means operates said controllable switch so that the charge on said capacitor varies in such a way so as to allow a continuously varying range of output pulse voltages on the output once said capacitor is discharged.
A method of operating an electric fence energiser, comprising the steps of:
- monitoring a perceived electrical load on an electric fence energiser;
- and
- adjusting a voltage on an energy storage capacitor of the energiser, wherein the adjustment of the voltage on the capacitor takes place in accordance with a pre-determined response to the perceived electrical load on the energiser, the pre-determined response allowing for a continuous range of output pulse voltages on an electric fence line once the capacitor is discharged.
An energiser for an electric fence and having an energiser output, said energiser comprising:
- an energy storage capacitor;
- switch means for controlling a charge in said capacitor;
- a control circuit connected to said switch means;
- and
- sensing means for relaying information to said control circuit regarding a perceived electrical load on the energiser output;
- wherein said control circuit upon receipt of the information from said sensing means operates said switch means so that the charge on said capacitor varies to allow a continuously varying range of output pulse voltages on the electric fence once said capacitor is discharged.
