Paper Abstract

In this paper, a new idea is put forward under the background that static high voltage DC power is commonly used to replace lightning in the femtosecond laser-guided lightning simulation experiment. We use a single chip microcomputer as the controller to generate controllable Pulse Width Modulation(PWM) wave signal,then through PWM control high voltage.So controllable high voltage in the femtosecond laser-guided lightning simulation experiment is formed by the method of weak voltage(namely PWM) controlling high voltage. In the experiment, the period and duty ratio of PWM output by the single-chip microcomputer are indirectly controlled by controlling the internal timer counter A, optocoupler and SCR are used as the safe isolation module between high and weak voltage. The experimental results show that the controllable high voltage in the femtosecond laser-induced high voltage discharge experiment can be easily and effectively obtained by adding a controller to control. At the same time, it can help us to analyze the influence of the different high voltages on the experimental parameters of femtosecond laser guided high voltage discharge.
