摘　　要：介绍一种用于永磁同步电机控制的转子位置检测方法。该方法采用新型旋转变压器/数字转换器AD2S1200,将旋转变压器输出的模拟信号转化为数字信号。分析了AD2S1200的工作原理,给出了同TMS320LF2407A的通讯接口方法及程序示例。A method of rotor position detection in permanent magnet synchronous motor（PMSM） control system, which transforms analog signals of resolver to digital signals using a novel resolver-digital converter AD2S1200, was introduced. The working principle of AD2S1200 was analyzed and a practical communication interface solution of hardware and software between AD2S1200 and TM320LF2407A was described in details.
