WebThe number of turns for both coils is just a ratio. Divide the output voltage by the input voltage. That will be your turns ratio. Keep in mind that the flyback circuit only generates an output pulse from the secondary winding when current is interrupted in the primary, in which case the primary voltage will exceed the input voltage by a large ... WebFeb 13, 2016 · 83 Switched mode power supplies use what is known as a "flyback converter" to provide voltage conversion and galvanic isolation. A core component of this converter is a high frequency transformer. Practical transformers have some stray capacitance between primary and secondary windings.
