摘　　要：介绍一种为高压脉冲氙灯（型号为４×６５Ｆ）而设计的预燃电路，电路采取开关电源方式供电，磁饱和方式降压、稳流。因此去掉了传统触发和预燃电路中的升压变压器、限流电阻、触发高压包等。整个电路的体积、重量明显减小，效率提高．实际运行表明，该电路工作可靠，运行稳定．A new pre-burning circuit designed for 4×65 F pulsed xenon lamas is Ptesented in this Paper. Since a half- bridge switching mode converter consisting of saturated transformer is employed, the step-up transformer, current-limiting resistor and trigger circuit which were involved in the previous circuit are no longer used in the new circuit. The volume and weight of the new circuit are obviously reduced while the efficiency is enhanced. The practical operation shows that this circuit is stable and reliable.
