摘　　要：针对三相同步器信号采集过程中偏差较大且剧烈跳动的问题,提出一种三相同步鉴相式采集及分区间解算方法,该方法首先通过鉴相方式判断励磁与三相电压相位关系,再进行A/D转换,最后通过分区间解算获取三相同步器角度值。为恶劣工业现场、机载环境等三相同步器信号的处理提供了一种低功耗、低成本、高精度解决方案。In order to solve the problems of large deviation and severe beating during acquisition of three phase synchronous signal,a kind of solution method of phase discriminator acquisition inter-partition is put forward.It judges the relation between excitation and three phase voltage by phase discriminator,then coverts to A/D synchronously,and gets the value of the angle for three phase synchronous signal through solution method of inter partition.The problem of acquisition bias can be solved effectively,which provides a solution for low power consumption,low cost and high-precision for signal disposition of three phase synchronous device in the harsh environment.
