Title: ELECTRIC FENCE ENERGIZING APPARATUS AND METHOD
Abstract:
An apparatus for supplying high-voltage pulses to an electric fence is disclosed, the apparatus comprising a rechargeable power supply (1); a voltage transformer device (3) to step up the voltage; a storage capacitor device (5) for repetitively being charged and discharged, the charging being performed by means of connecting the storage capacitor device to the voltage transformer device; and a discharge circuit (7) connectable to an electric fence and to ground, respectively, for repetitively delivering electric energy discharged from the storage capacitor device to the electric fence to thereby supply the electric fence with high-voltage pulses. The apparatus further includes a circuit (11) for measuring the voltage of the rechargeable power supply, and a control unit (9) adapted to control the repetitive charging of the storage capacitor device depending on the measured voltage of the rechargeable power supply to thereby save energy when the power supply runs down.
