摘要: An energy-efficient energizer for an electric fence for controlling livestock or the like, includes an output voltage sensor. By switching to extra storage capacitance and/or altering the charge voltage the energizer varies the duration of the output pulse and perhaps also the pulse voltage according to the sensed output, thus maintaining an effective livestock barrier and consuming high power only when required. Output pulses are about 8 kV (no load) down to 4 kV (wide range of loads). The control algorithm determines the capacitor charging time and initiates a charge sooner if a higher power pulse is to be delivered, so maintaining a constant pulse rate. The energizer includes a 12V DC power option and has a circuit for synthesizing a substantially unipolar pulse having low harmonic content.

摘要: A circuit (700) for an electric fence energizer (examples are 6 or 24 Joule versions) which synthesizes a pulse having a raised cosine waveform at a first or bus voltage uses a ferrite-cored output transformer (701) to multiply the voltage of the pulse to the required level. A raised cosine waveform has a low harmonic content and little filtering of high-power pulses is required in order to minimize electromagnetic emissions. On closure of a switch (707) in series with an inductor (705) a first capacitor bank (703) commences charging a second smaller capacitor bank (704) in parallel with the output primary and after the peak of the pulse any remaining charge is dissipated in a resistor (708) with the aid of a saturable inductor (702), acting as a switch. The saturable inductor may be the output transformer itself for lower output energizers. The output exhibits little or any reversal of polarity when matched to its load. The circuit may also be useful for applications such as strobe flashers in aircraft.

摘要: An energiser for an electric fence. The energiser includes, at least, one energy storage capacitor (14), a charging circuit (13) to enable the or each storage capacitor (14) to be charged from an energy source (10), semiconductor switching means (16), and control circuit means (15) to facilitate controlled turning -on and -off of the semiconductor switching means (16) to control the duration of the discharge from the energy storage means (14). In one form of the energiser a first semi-conductor switching means is arranged to connect in parallel the energy storage capacitors (14) to be charged and second semi-conductor switching means to connect two or more of the charged energy storage capacitors (14) in series to create an output pulse.

摘要: A data transmission system which is particularly useful for a remote control apparatus for an electric fence. The apparatus includes a portable hand held housing with a contact 16 which in use can contact a conductor of an electric fence line. The output of the apparatus includes a resonating circuit with inductor L, transformer 14 and a small high voltage capacitor C2. The apparatus can thus generate information embedded within a series of short signal bursts of a frequency within a predetermined frequency range. A receiver coupled to or forming part of an electric fence energizer can receive a signal from the apparatus to control operation of the energizer.
