Solve the following problems:
1. Refer to the given flyback converter circuit diagram. If Vo is 5V for a load resistor, Vin is 30V, N/N is 3, the magnetizing inductance Lmi is 500uH, and the switching frequency f is 40kHz, calculate the duty ratio D, average lin and Iout, and lin(0), lin, lout(0), lout as shown in Fig. 1. Assume lossless conditions.
