Flyback Converter with Transformer Leakage
This example shows the operation of a flyback converter.
The flyback converter is a buck-boost converter with isolation between its input and output. The inductor used in the buck-boost configuration is replaced by a transformer for isolation and storing energy before sending to the output via the output capacitor.
The theoretical transfer function of the flyback converter is:
where is the duty cycle, and , the turns ratio, is equal to .
