摘　　要：电源和功放是水下通信系统最重要的组成部分,设计了一种升压电源和功放电路,与传统的水声通信系统发射机相比,其输出电压更高、频率范围更广且体积更小。首先对经典Boost电路进行改进,设计了基于STM32的数控电源,再进行二次升压,实现了负载10 kΩ输出100 V和负载100Ω输出70 V的供电能力。将两块二次升压模块串联可输出电压±70 V,该电压为功放模块供电。功放模块最高工作频率为1.1 MHz,最大输出功率为40 W。最终电路实物尺寸为120 mm×120 mm×150 mm。通过水声通信实验,接收端成功解调出基带信号,验证了所制作高压电源和功放模块合理可行。Power supplies and amplifiers constitute the most critical components of underwater communication systems.In this paper,a booster power supply and amplifier circuit are designed for a hydroacoustic communication system.It has the characteristics of high output capacity and small size compared with the traditional transmitter of hydroacoustic communication systems.The improved booster supply is based on the classic Boost circuit for STM32-based digital control power supply.A twice boost is then applied to achieve an output of 100 V for a 10 kΩload and 70 V for a 100Ωload.Two secondary boost modules can be connected in series to output a voltage of±70 V,which supplies power to the amplifier module.The amplifier module has a maximum operating frequency of 1 MHz and maximum output power of 40 W.The dimensions of the final circuit are 120 mm×120 mm×150 mm.We designed a complete hydroacoustic communication experiment to verify that the fabricated high-voltage power supply and amplifier module design are reasonable and feasible and found that the receiver successfully demodulated the baseband signal.
