Optocoupler is an electronic component that has a light source at its input side and a light detector or sensor in its output side. A light source is a LED while the detector or sensor is a phototransistor. It is also called as optoisolator, photocoupler or optical isolator. This device is considered as a current controlled current source. This is
One of the usual applications of optocoupler is to provide isolation between two ground reference. That is why it is often seen in power supply feedback circuit. How to analyze optocoupler in feedback system is to discussed in this article. Keep on reading below. How to analyze optocoupler in feedback system is not as difficult as you think. However, the lack
