The preignition circuit consists of push-pull converter and high frequency transformer in order to ignite the pulse xenon lamp at a high pressure state with the principle of series resonance. The power supply has the characteristics of stable output, simple structure, small size, low weight and high efficiency. The results of experiment indicate that the power supply works stably and reliably and is suitable for all kinds of pulse xenon lamps.
