Problems solved by technology

However, due to the complex working principle of the pulse xenon lamp, it is greatly affected by the working circuit. Therefore, in the discharge circuit composed of general capacitors and inductors, it is difficult to obtain a circuit whose pulse width and pulse peak value meet the working conditions at the same time.

Generally, the pulse xenon lamp test circuit is only composed of a capacitor, an inductor and a charging power supply system. In order to obtain the required discharge pulse width and peak value, the inductance and capacitance must be adjusted repeatedly, and the charging voltage must be continuously charged to generate the required voltage. The current peak value is not only time-consuming and labor-intensive, but also limits the size and discharge parameters of the pulsed xenon lamp
