the control circuit of electric fence part 6

The impulsed voltage output circuit is composed by NAND gate in IC,field effect transistor VF and pulse transformer T.When the mains switch S gets through,the oscillator works.NAND gate D2 outputs oscillatory signal .It is buffered and processed by NAND gate D3 .Then it goes to the grid of VF.It conducts VE at interval time.It will generate about 200V impulsed voltage.It goes to the electric fence.It gives animals deterrence .You can adjust the resistence of RP,in order to change the working frequency of the oscillator.
