摘　　要：为了提高大功率TEA CO2激光器的工作性能,选用大功率旋转火花开关作为功率开关器件,制作了一种由高压谐振充电电路、高抗干扰的开关触发器、大功率旋转火花开关以及倒空式L-C反转电路等组成的脉冲激励电源。介绍了脉冲激励电源的设计方案,给出了电路工作原理,并对其在大功率TEA CO2激光器的实际工作进行了测试和评估。结果表明,所研制的脉冲激励电源可以满足大功率TEA CO2激光器的特殊工作要求,其重复工作频率可以在100～400Hz任意设定,输出工作电压可达40～50kV,电源平均功率>220kW,电源峰值功率高达1000MW。In order to improve the work performance of a high-power TEA CO2 laser, a high-power rotating spark switch is chosen as a device for power switchs. Therefore a pulsed exciting power supply is developed,which is composed of a high voltage resonant charging circuit, a high anti-jamming switching trigger, a rotating spark switch and a draw-out L-C reverse circuit. The design schemes of the pulsed exciting power supply are introduced and the circuit layout is presented. The measurement and the research of the power supply are conducted in the high-power TEA CO2 laser. The experimental results demonstrate that this pulsed exciting power supply developed by our lab can satisfy the special requirement of the high-power TEA CO2 laser, for it can offer the output working voltage up to 40-50 kV, the average power larger than 220 kW and the peak power as high as 1 000 MW, also for its repetition rate can be adjusted arbitrarily at the ranges of 100-400 Hz,
