| Electric Fence Circuit |
How to make a simple electric fence high voltage generator demo model circuit project using few components.This project is a demo science DIY homemade project for pest/animal repellant.
Components required
Ic - CD 4060
Resistor - 1kiloohms(3nos), 22 ohms,
- 220 kiloohms, 1 megaohms
Mosfet - IrfZ44
Ignition coil - Honda active scooter you can use any ignition coil.The more capacity and input current will give you more power output.
Working
The project is designed with the commonly available cheap ic cd4060.In other words it's the heart of the circuit.This ic works as square wave oscillator mode so that the circuit oscillate on and off continuously.This generates a square wave frequency at the output of ic.The number of times it should on/off(frequency) is determined by resistors R3 and R4.The frequency generated is around 1 kilo hertz.
The output signal is then fed to a mosfet which drives the final transformer.The transformer used here is an ignition coil of Honda activa scooter.We can use any ignition coil.This ignition coil is found very cheap in price which can buy this from an automobile shop for around 4-5 dollars.
The power supply used here is a 12 volt 1 ampere only.The voltage and current given to the ignition coil determines how much power is delivered to the output environment.
Note:
» We can give supply of 12 volt 5 ampere for getting more power output from the ignition coil
» Ignition coil with more power handling is available in market
» Always give heat sink to the mosfet as it's driving a transformer the mosfet will get heated up.
» Use more number of mosfet in driver circuit.If we need to get more power output from the circuit
» Timer can be used along with the circuit and thus we can control the on/off timing according to the application.
» While working don't touch anywhere in the circuit.
» Donot give the output from ignition coil to any electronic devices as it may permenantly damage the device.
Applications
» Used in pest repellent for farmers in crops
» This high voltage circuit can act as a driver circuit of ignition coil in vehicles.
» This sparks can destroy insects,mosquitoes etc.
» This is widely used for removing wild animals/birds
