Feedback circuit composed of optocouplers
Optocouplers provide a mechanically-robust isolation barrier with very high voltage ratings (e. 5 kV) in a small package size, helping the power supply to meet stringent safety standards. The optocoupler is then part of the control loop, and more exactly, of the compensator. The solution to this problem is a combination of circuit topology, layout, and supply control. Specifically, it will cover control techniques using standard phototransistors and a new. Optocouplers are critical in switch-mode power supply (SMPS) designs, enabling safe and reliable signal transmission across galvanic isolation boundaries. To work well, they need to be correctly connected and used in the feedback loop.
