The working principle of the invention is as follows:
The input power supply provides required voltage for the MCU controller U1 through the LDO chip U2, and the first electrolytic capacitor EC1 is a filter capacitor of the voltage of the MCU controller U1. The MCU controller U1 receives the current flowing through the first resistor R1 to generate voltage feedback, then the MCU controller U1 sends PWM signals with proper frequency to the power tube driving chip U3, the fourth resistor R4 is a pull-down resistor and is used for stabilizing the PWM signals sent by the MCU controller U1, and the power tube driving chip U3 drives the power tube Q1 to work according to the PWM signals. The second electrolytic capacitor EC2 and the third electrolytic capacitor EC3 are filter capacitors of an output power supply, the input power supply is connected to the power tube Q1 through the primary end and the other end of the first transformer L1, and when the power tube Q1 is turned on, the voltages at two ends of the first resistor R1 are gradually increased. The voltage is fed back to the MCU controller U1, and when the voltage is increased to a certain value, the MCU controller U1 adjusts and sends out PWM signals, so that the aim of controlling the output power of the power tube Q1 is fulfilled.
The second diode D2 and the third capacitor C3 form a rectifying circuit, the voltage value is the voltage at two ends of the third capacitor C3, the sixth resistor R6 and the seventh resistor R7 are voltage release circuits of the third capacitor C3, when the voltage at two ends of the third capacitor C3 reaches the ignition voltage value of the igniter DS1, the igniter DS1 is instantly turned on, and at this time, the inductance between the third capacitor C3 and the primary end and the other end of the second transformer L2 generates LC oscillation. The third diode D3 filters out the negative voltage of the LC oscillation, and when the LC oscillation is generated, the inductance of the secondary side and the inductance of the other side of the second transformer L2 also generate oscillation as the capacitance. At this time, resonance occurs, and the electric quantity on the third capacitor C3 is transferred to the terminal T1 and the terminal T2 according to a certain proportion, and at this time, the voltages at the two ends of the terminal T1 and the terminal T2 are the required high voltage. After the electric quantity on the third capacitor C3 is transferred out, the voltage is reduced, so that the igniter DS1 is disconnected, and resonance stops. The third capacitor C3 is boosted again by the first transformer T1. The charging and discharging process of the third capacitor C3 is repeated, and the charging time is relatively long due to the short discharging time, so that pulse voltages are formed at two ends of the terminal T1 and the terminal T2.
The pulse voltage can reach more than 50KV, the output current can be controlled below 3mA, the pulse width can be controlled below 50us, and the pulse frequency is stable and controllable. For example, the voltage can be controlled to be about 20PPS (20 high voltage pulse cycles per second) as required.

The invention has the advantages of high output pulse voltage, narrow discharge pulse width, stable and controllable pulse frequency, etc., thus not only achieving the purpose of riot control, but also being effective and safe without causing harm to human body. The invention has simple structure and small volume, and can be conveniently embedded into various non-fatal antiriot devices.
