摘　　要：本文设计的自整角机／旋转变压器数字转换器是一种将自整角机／旋转变压器的轴角信号转变为数字角的系统装置。主要是通过隔离放大器将自整角机／旋转变压器输出的信号电压及参考电压进行隔离放大，隔离以后的信号送到A／D转换器中，AID转换器对其输入的模拟信号进行变换并将变换的数据送到单片机中，存放在单片机内部的RAM存储区，由单片机对数据进行处理，得出数字角并输出。本设计电路简单，转换精度高，可靠性高，功耗低，误差小。In this paper, the design of synchro/resolver is a transformed AC voltage signal output for digital angle device.Mainly through the isolation amplifier to insulare and to enlarge the signal voltage and the reference voltage of the seisyn/resolver＇ s transformer outputred, which are transmitted to the AID converter with reference voltage signals. Having been converted into data form, they are inputted the MCU and stored in its internal RAM storage area for further data processing.The merits of this design has simple circuit, high precision, high reliability, low power consumption, and small deviation etc.
