In view of the short range and insufficient deterrent effect of the existing electroshock weapons, this paper designs a boosting system using small electroshock bullets for 18.4 mm shotguns. The use of zero-voltage switching technology in the inverter circuit will be carbon-based battery output DC converted to high-frequency alternating current, the use of doubling rectifier technology for boosting and AC/DC conversion, so that the output voltage value of the entire system to reach more than 10 kV. Meanwhile, the miniaturisation of the electroshock projectile circuit is designed to meet the needs of the 18.4 mm shotgun launcher launching. The experimental results show that the electric shock projectile designed in this paper can continuously output the voltage of 11 kV, the frequency is 50 Hz, which meets the design index requirements and can provide effective technical support for the engineering improvement of electric shock weapons.
