摘要
针对功率因数校正系统对实时数据处理要求,设计了一个高速数据采集系统,并将该系统应用于功率因数校正系统的数据前端采集中。该系统采用AD7874和高速FIFO,使用NiosII软核处理器实现SOPC设计,与现有方法比较,系统具有硬件结构紧凑,控制性能优良,工作可靠性高,可移植性好的特点。文中对其进行了较深入的仿真研究,表明检测效果良好。
According to the requirement of the real-time data processing in power factor correction system,a high speed data acquisition has been designed,and it is used in the front data acquisition.The AD7874 and high speed FIFO are utilized in it,and the SOPC is designed by the soft-core processor Nios II.Compared with the current methods,this system is characterized by compact structure,good control performance,high reliability and excellent transplantation.A deep simulation is made.The simulation results show that the detection effect is perfect.
