Flyback Converter Transfer Function. D d n n v v. 12 flyback converter as explained earlier flyback converter is obtained by replacing inductor with transformer in a buck boost converter.
Looking from the primary side the voltage across the primary is equal to the output voltage divided by the turns ratio. Finally we ll apply this method in two real switching power supply. Since vs vinsnp and from 4.
The theoretical transfer function of the flyback converter is.

In the flyback transformer as mentioned above regulation is accomplished by pwm. The transfer function of the power circuit in red and its target loop gain in blue. Eventually the high precision compensation circuit is simulated.
