High voltage electric fence circuit

A safe high-voltage defense grid is a facility that restricts the entry and exit of people or livestock in specific areas and protects certain targets. When people
or livestock touch the power grid, they will suffer involuntary severe electric shock, but it is not life-threatening. Safety defense power grids generally
use high-voltage pulse electricity. As a power grid that restricts people, since the energy discharged by the power grid to the human body will cause convulsions when it reaches 1/4J, and
when it exceeds 1J, it can be life-threatening. Therefore, a safe high-voltage power grid must control the energy released by each pulse.
It is a high-voltage electric fence, which can output high-voltage pulse voltage of tens of thousands of volts.
    The pulse transformer T2 can be modified with a 23-30cm TV output transformer. The primary ∞1 is
wound with 70 turns of enameled wire with a diameter of 0.47mm, and the original high-voltage package is used as the secondary.
