Flyback Converters In Problems 8.1 through 8.4, in a Flyback converter, Vin = 30V, N1 = 30 turns, and N2 = 15 turns. The self-inductance of winding. The output voltage is regulated at Vo = 9 V.
1. For the same duty-ratio as in problem 8.1, calculate the critical power which makes this converter operate at the border of incomplete and complete demagnetization modes.
2. Draw the waveforms, similar to those in Problem 8.1, in Problem 8.2.
3. Consider that a Flyback converter is operating in the complete demagnetizing mode. Under this mode of operation, derive the voltage transfer ratio in terms of the transformer magnetizing inductance Lm1 seen from the input-side winding, switching frequency fs the duty-ratio D, and the load resistance R.
