ABSTRACT

Design and measurement results of the signal converter with three-phase and quadrature outputs are presented in this paper. Input to the converter is a sinusoidal reference signal and the outputs are the quadrature and symmetrical three-phase sinusoidal signals of the same frequency as the reference. The output amplitudes are proportional to the reference amplitude. The quadrature output is generated in the novel phase-shift controlled all-pass filter, while the three-phase outputs are generated from the quadrature and reference signals in the electronic implementation of the Scott-T transformer. The converter is of all-analog design and is intended for driving receiver (Rx) type synchros and resolvers during testing and students hands-on laboratory experiments in the frequency range 50 Hz–5 kHz.

摘要

本文介绍了具有三相和正交输出的信号转换器的设计和测量结果。转换器的输入是正弦参考信号，输出是与参考频率相同的正交对称三相正弦信号。输出幅度与参考幅度成比例。正交输出在新颖的相移控制全通滤波器中产生，而三相输出由 Scott-T 变压器的电子实现中的正交和参考信号产生。该转换器采用全模拟设计，用于在测试期间驱动接收器 (Rx) 型同步器和旋转变压器，以及在 50 Hz–5 kHz 频率范围内进行学生动手实验室实验。
