摘　　要：介绍了一种1.1m长氙灯的双余弦脉冲合成点火技术。设计了双余弦脉冲合成点火电路和双余弦脉冲合成变压器的结构,通过点火变压器初次级余弦脉冲谐振分析,选取放电电容值;通过磁性材料的选择和初级线圈的计算,双余弦脉冲合成变压器先工作在非饱和区,作为点火变压器,然后工作在饱和区,作为氙灯放电的成形电感。最后进行了双余弦脉冲合成波形的测量,测量结果和设计值相符合。双余弦脉冲合成技术,可以解决单个点火变压器绝缘难的问题,获得更高的点火电压,点燃比较难电离的气体灯,点燃可靠且同步精度高。此技术现已用于点燃长1.1m,直径26mm的气体氙灯。A ignition technology for 1.1 meters long xenon lamp based on double cosine pulse synthesis is introduced. The ignition circuit of double-cosine pulse synthesis and structure of double-cosine pulse transformer are designed. By analyzing on cosine pulse resonant, the capacitance value for discharge capacitor is chosen;and magnetic material is chosen by calculating primary turns and secondary turns. The double-cosine pulse synthesis transformer works at unsatu-rated zone as ignition transformer firstly;then works at saturated zone as wave forming inductor of Xenon Lamp. Final-ly, the double-cosine pulse waveform synthesis being measured, the measurement results and design values are equally with each other. The technology of double-cosine pulse synthesis, the insulation of single ignition transformer can be easily solved;higher ignition voltage is got;the gas lamp which is difficult to ionize is ignited. The ignition technology is reliable and have high-precision synchronization. Now, this technology has been used to ignite a 1.1m long Xenon lamp with 26mm diameter.
