1 The basic program of Solar electric fence power supply

 Solar electric fence power circuit principle diagram as shown in figure 1, this power supply mainly madeup by the solar cell module, cycle controller, batteries, high pressure pulse generator and wire fence. The sun battery output battery in the sun light, through the charging and discharging controller to contral the battery to charge and discharge, high pressure generator let low pressure  DC power change to into about 5000 V inverter high pressure pulse output to the fence line, when animals hit fence line, and it can produce shock make animals feel psychological produce reflex, and when see the fence line will be afraid, and stay away from the fence line, so achieve to protect their crops or livestock farms as the function.

2 solar electric fence power points of design 

2.1 Part of the design of solar-powered

      According to the local month average in day total radiation and load size, through the computer program design, make sure the sun battery power is 65 W, the capacity of the battery is 12 V, 100 Ah.

     According to local meteorological conditions, solar cell module selection  36 125 mm x 125 mm polycrystalline silicon solar cell encapsulation components.

     Battery choose 12 V, 100 Ah suitable for solar power no-maintenance lead-acid battery.Charging and discharging controller has charging protection, discharge protection, prevent glance meter protector against fraud charge, and other functions, to ensure that the system to specific long-term reliable work.The detial index  are as follows.

Low voltage disconnect point 10.8 V
Restore power voltage 12.3 V
Disconnect point of charging 14.3 V
Restore charge voltage 13.6 V
Temperature compensation coefficient 3.5 mV / ℃

2.2 the design of high voltage pulse part 

 To make part of the driver as the core part of the UC3526PWM chips. UC3526 two ways of output from the push-pull part of the Lord are switching devices, through the transformer boost, output about 5000 V the high pressure pulse, high pressure pulse width adjusted by the  potentiometer on the power supply enclosure.
     1) high pressure pulse voltage is about 5000 V, but current is small, discontinuous, for human and livestock and animal no fatal injury.
     2) pulse width can be adjusted to try to minimize the energy consumption of the work, and to achieve purpose.
