The research and design of high-voltage electrostatic pest killer The generation method of high-voltage electrostatic is studied and analyzed, and the appropriate scheme is selected according to the actual situation. From this, we can select the required electrical components and parts, and design the main circuit, control circuit, working circuit, etc. of the pest killer. Finally, on the basis of design, integrate the circuit composed of electrical components into a circuit board, and arrange the control switch, power supply, etc
