摘要
通过ARM控制器,以FPGA实现DDS作为驱动电源控制器及信号发生器,并通过集成高压运放,实现超声波传感器探头的电源激励。该方法电源频率调节可以使超声波探头工作在稳定状态,具有稳定性高、动态响应快等优点。
The paper through the arm controller,based on FPGA realization of DDS as driving power supply controller and the signal generator,and an ultrasonic sensor probe excitation source was realized through the integrated high voltage amplifier. The power frequency regulation of the method can make the ultrasonic probe work in stable state,with the advantages of high stability,fast dynamic response,and so on.
