Compensating Optocoupler Feedback in Flyback Converters

SPONSORED BY:

The flyback DC/DC converter is an isolated switching power supply topology that is often used for output powers below 150 W. Such 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.
