Pulsed xenon lamp power supply

The synchronous lighting source of high-speed photography is a kind of high brightness flash light source which uses the pulsed xenon lamp as the output load. Its driving circuit adopts pulse forming network PFN circuit, using Orcad Pspice software to simulate the discharge current of FFN, its simulation result has certain guiding significance. The power supply has the function of manual trigger and synchronous trigger, the front and back edges of the output pulse have good time response. The charge voltage of xenon lamp is 0~3.5 kV, and the delay time of trigger signal and optical waveform is 125 μs with light wave shape. The design principle and technical scheme of the power supply are proved by the experiment.
