摘　　要：设计了一种电压可变和频率可变,且适用于无机电致发光片的测量电源,该电源主电路采用降压斩波、全桥变换等技术,可以进行过流保护、峰值电压检测,电源工作稳定,性能可靠.以该电源为基础,给出了无机电致发光动态亮度的测量方法,在4450型样品上进行了试验,测得其亮度随电压频率变化的滞迴特性.A measurement power supply has been designed and made, which applies measurement of Inorganic electroluminescence film. Its output voltage and frequency can be variable, whose main circuit adopted technology such as buck chopper and full-bridge converter. The power supply also adopts technology such as over-current protection, peak voltage detecting. All of these technologies make the power operate on a stabilization condition and its performance is credible. The measurement method of Inorganic electroluminescence development brightness has been given. The experiments has been done in 4450 specimen, variable properties of brightness with voltage and frequency were obtained.
