  • The power supply of the pulse xenon lamp is a key device in high-speed photography test system. Based on the analysis for the parameters of the pulse xenon lamp with a length of 540mm, a diameter of 18mm and a gap of 250mm, a pulsed xenon lamp power supply developed with manual trigger and external trigger functions, xenon lamp charging voltage 2.5~4.5 kV and output pulse current amplitude 3~6 kA with the pulse width of 230 s. Experimental results are given in the case of single trigger. The power supply system adopts the phase shift control of the thyristor to control the voltage regulator module and charges the capacitor linearly. IGBT power semiconductor switching device generates a pulse signal, and the set-up transformer amplifies the signal to trigger the xenon lamp, then the xenon lamp is turned on to emit light. With control signal isolation and capacitor grounded at the end, the method suppresses the effective artificial ground potential, improves the reliability of power supply and anti-electromagnetic interference ability. Hundreds of experiments show the power supply triggers the pulsed xenon lamp with 100% reliability.
