High-voltage pulse generator

As shown in the figure, the circuit can generate a high voltage pulse using a 6V~12V DC power supply. The transistors VTl and VT2 in the circuit form an oscillator, which generates a DC pulse voltage with a frequency of 3Hz and outputs a primary coil of a 6V:240V booster with a transformation ratio. At the end of each pulse, a high voltage is generated in the secondary coil of the transformer accordingly. The repetition frequency of the pulse can be adjusted by selecting the values ​​of C2 and Rl. When this circuit is used in a baton, a lead-acid battery can be used.
