Figure 1: Power stage of the flyback converter (simplified)

Eleazar Falco, FAE, Würth Elektronik eiSos / Editor, Gerhard Stelzer

Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design. The flyback converter is an isolated switching power
