An alternative to magnetic isolation is optical isolation, which is conceptually simple: the input side drives an LED, the output of the LED impinges on a co-packaged phototransistor, and the output is the phototransistor current (Figure 6). The short optical path between LED and phototransistor ...
Galvanic isolation separates two electrical circuits where there is no flow of electrons. This isolation can perform the physical partition between the input & output. By adding this isolation among two systems, it can remove all the surge & grounding problems. Before adding isolation, the two sys...
