This simple circuit provides better than 1% accuracy in optically coupling a DC voltage signal. To compensate for the non-linearity of the optical isolator, an identical device is connected in the ...

This file type includes high-resolution graphics and schematics when applicable. Did you know that your shunt regulator is in danger? Don’t worry—the fix is free (and free is good). A feedback circuit ...

In traditional isolated high voltage flyback converters, tight regulation is achieved using opto-couplers to transfer regulation information from the secondary-side reference circuitry to the primary ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

Once more opto-isolators are to be seen in Wonderland. The aim was to see if the faster photodiode types can operate quickly in common collector mode. They consist of an infra-red led and a fast npn ...
