Optocoupler Types, Applications with Examples and
An optocoupler is a component that uses light energy to connect two different electrical circuits or transfer energy from one circuit to another circuit.
Optocoupler Circuit Design and Detailed Analysis
Optocoupler circuit design is not that difficult as some thought. Once you know what a CTR is and learn how to use it, then Optocoupler circuit design is that easy.
Zero Crossing Detector
Protection diode: These are simple diode which is used to prevent the op-amp from the high input gain, because here we use direct input voltage.
Relay to switch two inputs separately to single output
This is where break-before-make matters to avoid shorting outputs. Interlocking (both commands must not be active at once): Two inputs exist, but the circuit must reject “both on.” Example:
