摘要
Multisim提供了许多便捷功能,但其在正弦稳态等电路分析中不能直接测量电压相位差。为解决这一问题,设计了基于运放电路和软件自带工具的相位差测量电路。介绍了电路的组成及工作原理,通过对所设计电路本身和实例电路的仿真进一步说明电路的测量方法,同时对电路中相关参数的误差进行了详细分析,结果表明该电路测量频率范围宽、精度高,可用于相位差电路的直接测量。
As a kind of powerful EDA simulation software,Multisim offers a lot of convenience functions,but it can not directly be used in phase difference measurement of the sinusoidal steady state circuit and so on.In order to solve this problem,a new circuit is designed to measure the phase difference,which is composed of the amplifiers and the software tools.The circuit constituent and the work principle are introduced,the simulation of the design circuit and the living example show further the method of measurement,and we analysis the error of the related parameters in detail,the result indicates that the phase deference measurement circuit with broad frequency range and high precision can measure the phase deference directly.
