A nonideal flyback converter. The flyback converter shown in Fig. 6.32d operates in the continuous conduction mode. The MOSFET has on-resistance Ron, and the diode has a constant forward voltage drop Vp. The flyback transformer has primary winding resistance Rp and secondary winding resistance Ry. (a) Derive a complete steady-state equivalent circuit model, which is valid in the contin- uous conduction mode, and which correctly models the loss elements listed above as well as the converter input and output ports. Sketch your equivalent circuit. (b) Derive an analytical expression for the converter efficiency.
