基于PIC的航空电源相序检测器的设计

摘要

在不改变连接设备原有硬件的情况下,采用单片机PIC12F675为控制核心,设计了一套具有保护和故障指示功能的115 V/400 Hz航空三相交流电源相序检测器,分析了电路的结构组成以及工作原理,给出了相应的软件流程,同时在multisimll.0中建立相应的仿真模型进行仿真验证.%A set of the three-phase 115 V/400 Hz AC power phase sequence detector is designed. In condition of unchanging connected devices in the case of the original hardware.the detection accomplishes the functions of protection and fault indication, with the PIC12F675 as main microcontroller. Analyzing the circuit structure and its working principle, the corresponding software process is presented,and multisimll. 0 is used to create the corresponding simulation model for simulation.
