摘　　要：该文介绍了BOOST电路的工作原理并基于低压芯片TPS61175设计了一款可调动态范围广、输出纹波低的APD偏压驱动电源,进行了理论计算、仿真分析及实验验证。实验结果表明,在5~12 V的输入电压下,可调输出电压范围达21.73~178.2 V,最大输出纹波为17.6 mVpp,小于输出电压的0.1%,可满足大部分型号的APD对反向偏置电压的要求。此电源通过调节不同的反向偏置电压,可使APD工作于不同的模式,具有体积小、纹波低和成本低的优点,可应用于激光测距、微光成像及光模块的设计中。The working principle of Boost circuit is introduced.Based on the low⁃voltage chip TPS61175,an APD drive power supply with wide adjustable dynamic range and low output ripple is designed.The theoretical calculation,simulation analysis and experimental verification are carried out.The experimental results show that under the input voltage of 5~12 V,the adjustable output voltage range reaches 21.73~178.2 V,and the maximum output ripple is 17.6 mVpp,which can meet the requirements of most types of APD for reverse bias voltage.By adjusting different reverse bias,APD can work in different modes.It has the advantages of small volume,low ripple and low cost.It can be used in laser ranging,low light level imaging and optical module design.
