摘要
根据CO2激光器气体辉光放电的负阻特性,研究设计了一种新型零电流准谐振高压激励电源。该电源采用电压电流双环控制策略,复合式全波倍压整流输出,不仅降低了对高频变压器绝缘与工艺方面的要求,同时稳定性、效率也得到了提高。
According to the negative resistance characteristics of glow discharge of CO 2 laser,a novel zero current quasi-resonant high voltage excitation power supply is researched and designed.The dual-loop feedback control technology and voltage doubling rectifing circuit of combined type full-wave are used to the laser power supply.Which enhance not only insulation and performance for high-frequency transformer but also increases stability and efficiency.
