modelFlybackConverter
A single output flyback converter, built of nonideal (lossy) elements.
Losses of a transistor, diode, winding resistance,core losses and
magnetizing current are modeled. Optionally any lossy element can be
set to 0.
The duty cycle is set directly (as a dimensionless real number
between 0 and 1) and may vary during the simulation run.
Extends from ISmpsDport ( An extension of SMPS.BasicConverter.ISmps with an aditional input port that allows direct setting of the duty cycle ratio (D). ).
