A high-voltage single-pulse generation system belongs to the fields of software development and electronic engineering. This invention mainly comprises two subsystems: a software system and a hardware system, which are connected and transmit data via a USB cable. The hardware system consists of three parts: an Arduino development board, a high-voltage switching circuit, and a high-voltage DC power supply. The user precisely sets the required pulse width of the high-voltage single pulse in the software and then transmits this pulse width information to the Arduino development board in the hardware system. The Arduino development board emits a single low-voltage pulse with a peak value of 5V and a pulse width identical to the value set in the software. The high-voltage switching circuit receives the single low-voltage pulse information emitted by the Arduino development board and drives the opening and closing of the high-voltage relay contacts in the circuit according to the pulse width. The high-voltage DC power supply provides the pulse peak value for the system. Through the organic combination of the software and hardware systems, a single high-voltage pulse with precisely adjustable pulse width and peak value can be generated. This system is low-cost, easy to implement, highly practical, and easy to promote.
