Electric Fence Circuit Diagram 555

This is a more complex design than my c mos electric fence on my site.

Electric fence circuit diagram 555.

It uses 2x 555 timers one runs in astable mode and is used to generate the frequency interval while the second one controls the pulse length and so the output voltage. Here 555 timer ic is in astable mode and a preset time delay is provided by r3 r5 and c1. I will use this sircuit for my electric fe. In the circuit diagram we see that the entire circuit is basically comprised of four stages.

With the coil i use and set for the greatest pulse output the output is 22 000 volts. A circuit design to drive a car ignition coil with single to multiple burst pulses. Did not use a pn2222 in between the 555 and mosfet. A standard 12v 7ah sealed maintenance free smf ups battery is required for powering the entire unit.

According to the circuit diagram when ldr detects any activity the output of the op amp ic goes low and pnp transistor t1 start conducting. Now i did use a mosfet in place of the 2n3056 driven directly from the 555 via a 330 ohm resistor i e. In this video i will show how to make driver for ignition coil. High voltage is generated by this device.

This is extremely dangerous and can kill human beings and even huge land animals like elephant instantaneously. Replace the 1 cap on pins 2 6 of the 3rd 555 with a 001 hotter picture overlay. I built your 20kv electric fence circuit which works very well except every two or three minutes the 2nd 555 u2 goes u s. Some property owners try to construct their own electric fence to skip the equipment cost by connecting a live 230v or even 440v to the metallic wires which run around their property.

Hence the led starts glowing and the 555 timer ic get triggered. Electric fencing circuit has very low energy. A dc oscillator stage an intermediate 12 to 230 volts step up stage the voltage collector and firing stage and the super high voltage booster stage. The circuit runs on 12v batteries making this a very portable fence energizer solution.

If not the arrangement will not work as it ought to be. A calculator for the 555 timers can be found here. The circuit of a simple electric window charger. Let s diagnose the proposed electric fence charger circuit more deeply.
