modelCukConverter

An non-isoltaed Cuk converter, built of nonideal (lossy) elements. Losses of a transistor, diode and inductor copper are modeled. Optionally any lossy element can be set to 0. By default both inductors and capacitors are identical. 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). ).
