摘　　要：研制了一种可用于驱动介质阻挡放电平面光源的电源电路,并对其工作过程进行了理论分析,同时对介质阻挡放电平面光源的亮度及发光效率的影响因素进行了实验研究。结果表明,电路的开关频率、输入电压和输出波形占空比对光源亮度和发光效率均有很大影响。Dielectric barrier discharge（DBD） flat lamp has a cheerful prospect in many areas such as backlight for LCD, lighting and personalized decorative since it is environmental, long life and has a short response time. In this paper, a switching power supply circuit, which can drive the DBD flat lamp efficiently, was developed. Moreover, the operating principle and the influence on brightness and luminous efficiency of DBD flat lamp were analyzed and performed by experiment. Based on the analysis and experiment, the switching frequency, input voltage of circuit and duty cycle of output waveform has a great impact on brightness and luminous efficiency.
