The AC 220V voltage is reducted by T1 isolated.It is commutated by VD1-VD4.It is filtered by C1.And it is current limited by R1.It charges C2.It is branched by R2,VS,RP and R3.It provides trigger voltage for VT's gate.When the voltage of C2 is charged to a certain value,VT is triggered to conduct.C2 discharges on VT and the first winding of T2.After C2 discharges,VT stops.C2 begins to charge,so VT conducts……It goes over and over again.It will generate kilovoltage pulsed high voltage on the second winding of T2.The high voltage of the electric fence will give the animal touching it an electric shock.
