线性光耦器件IL300-F-X009原理及其应用

介绍在采集交流永磁同步电机母线电流时,为防止外界的各种干扰,必须将霍尔传感器测量系统和DSP数字微处理器进行电气隔离。为了能更精确地传送模拟信号,进行电压检测,用线性光耦（IL300-F-X009）隔离是最好的选择。线性光耦输出信号随输入信号变化而成比例变化,它为模拟信号传输过程中,隔离电路的简单化、高精度化带来了方便。

The Principles and Applications of Linear Optocoupler IL300-F-X009

This article describes that when collecting the bus current of AC permanent magnet synchronous motor and preventing a variety of outside interference,the Hall sensor system and DSP digital microprocessor must be electrically isolated.In order to more accurately transmit analog signals,the isolation with a linear optocoupler（IL300-F-X009） is the best choice.Linear optocoupler output signal is changed in proportion with the change of input signal;it is convenient for the simplicity and high precision of isolation circuit during the analog signal transmission process.
