摘要
为了对旋转变压器(简称旋变)的信号进行仿真,通过使用AVR单片机ATmega16和AD5293实现一种电阻式数字旋变的电路设计。利用SPI总线对AD5293进行通信及设置。数字旋变模拟输出旋转变压器产生的正弦信号和余弦信号,可替代真实的旋转变压器,达到测试解码解算电路的目的。经试验验证,该设计适用于旋转变压器的仿真。
In order to simulate the signal of a rotating transformer （＂resolver＂ for short）, the circuit of a digital resistance resolver is designed based on AVR MCU ATmegal6 and AD5293. The AD5293 is initialized and configured through the commu-nication of SPI bus with MCU. The digital resolver can output sine signal and cosine signal produced by the resolver and can re-place the real resolver for the purpose of testing the decoding and resolving circuit. The experiment shows that the design scheme is suitable for the simulation of the resolver.
