Optocouplers for AC & DC

Power Electronics / Patnaik UC

Optocouplers are used mostly in power electronics circuits to isolate the fatal mains utility voltage to that of the low dc voltage that the control circuit works. Therefore some call it optoisolators. They find use in control circuits feeding Thyristors,MOSFETs,IGBTs. Submitted below an audio visual for better understanding.
