in order to improve the quality of aircraft power system, the AC sampting technotogy is sludied. AC sampling technology is used to collect real time adjustment point voltage and other parameters Then through digital signal processing algorithm the collected data is analyzed and also the working state of the power supply system is monitored. TMS320F2812 is used as core of controller. The test results show that the system has higher precision and reliability and it is meaning ful in the devclopment of digital aircraft power system.%为了更有效地提高飞机供电系统的质量,本课题对交流采样技术在航空电源上的应用进行了研究.提出了一种通过交流采样实时采集调节点处电压等电力参数,通过数字信号处理算法对采集到的数据进行数值分析,有效地监控供电系统工作状态.系统采用TMS320F2812控制核心.试验结果表明:该系统具有较高的精度和可靠性,对国内航空电源系统向数字化方向发展具有较高的使用价值.
