摘　　要：本文在分析ＣＯ＿２激光器对电源性能要求的基础上，利用电感和电容对电流移相和回路产生谐振的原理，研制出ＬＣ移相双变压器式ＣＯ＿２激光电源。该电源接入单相网路电源时，无需在高压端接入任何形式的滤波电路和限流电阻，可输出波纹系数小于４％的直流波形，并能长期稳定工作，工作电流变化量小于±０，１ｍＡ，转换效率高达９０％以上。Based on the study of the functions of power supply which are requlred by CO_2laser,a LCphaseshift-double transformer power supply for CO_2 laser has been designed and manufactured in this paperwhich applied the principles of phase- shift and harmonic oscillation produced by inductance andcapecitance. It cna supply stable,continuous current with ripple factor less than 4%and work stably for along time without any forms of filters and current limiting resistance in the high voltage end even ifconnected a single- phase network service. The change of working current is less than±0.1mA,Thepresent power supply has the electrical transforming efficiency as high as 90%.
