The Flyback Converter - University of Colorado Boulder
ecee.colorado.edu4 Solution for the conversion ratio then leads to M(D)=V V g = n D D' (6) So the conversion ratio of the flyback converter is similar to that of the buck-boost converter, but contains an added factor of n. Application of the principle of charge balance to the output capacitor C leads to i
