摘要
设计了一种具有升压和自动温度漂移补偿功能的雪崩光电二极管(APD)偏置电压模块,该模块包含正反馈振荡器、高频全波整流电路和温度补偿器。正反馈振荡器实现DC/AC的变换,并通过变压器进行电压放大;高频全波整流电路通过AC/DC变换输出直流高压;温度补偿器通过模拟温度传感器自动补偿APD的温度漂移。该模块大小为1.7cm×2.7cm,最大功耗为100mW,输出电压在0~372V连续可调,且最大纹波不超过0.004%,通过对模块中元器件参数的调整,能够对任意型号的APD进行电压偏置和温度补偿,偏置电压最大偏差不超过0.005%。
An APD bias voltage module with voltage boost and automatic compensation for temperature drift was designed.The module includes a positive feedback oscillator,a high frequency full wave rectifier circuit and a temperature compensator.Positive feedback oscillator is used to achieve DC/AC conversion,and the transformer is used to amplify voltage.Highfrequency full-wave rectifier circuit outputs DC high voltage through AC/DC conversion.The temperature compensator automatically compensates the temperature drift of APD by the simulate temperature sensor.The size of the module is 1.7 cm×2.7 cm,the maximum power consumption is 100 mW,the output voltage is continuously adjustable in 0~372 V,and the maximum ripple is not more than 0.004%.By adjusting the parameters of components in the module,the bias voltage and temperature compensation can be carried out for any type of APD,and the maximum deviation of bias voltage doed not exceed 0.005%.
