An optocoupler (or optoisolator) is a device that galvanically separates circuits and is not only great at isolation but allows you to interface to circuits with different ground planes or that ...

This simple scheme is based on the circuit shown below (Figure 1) in my recent article [1]. Figure 1 Using common transistor optocoupler to achieve a tube-like sound. It is known that the main feature ...

The junior system designer often places the system's power requirements at the end of the list, and thus overlooks the importance of an isolated, versus non-isolated AC/AC, AC/DC, DC/AC, or DC/DC ...

Optocouplers frequently fail without a sound in labs or during repairs. The package appears to be undamaged, but there may be no output from the LED source or the photosensitive output stage. Testing ...

The importance of signal isolation in high-voltage design The difference between optocouplers and opto-emulators Details on TI’s silicon dioxide (SiO 2) isolation technology Isolation is invaluable in ...

Abstract: Optocoupler is applied to isolate the control loop to the main power stage, and transfer feedback signal in the negative feedback loop of SMPS. But due to surface deterioration and the ...
