A flyback converter is to be designed so that it operates in continuous "current" (flux) mode with a duty cycle of D = 0.45 when input voltage Vs = 48 V, output voltage Vo = 30 V, switching frequency fs = 25 kHz, and load resistor R = 15 W. Determine the necessary transformer turns ratio and transformer magnetizing inductance that will make the minimum inductor current to be 25% of the average. Confirm your answer with PSIM.
Q. A 20-kVA, 2200:220-V, 60-Hz, single-phase transformer has these parameters: Resistance of the 2200-V winding R1 = 2.50 Resistance of the 220-V winding R2 = 0.03 Lea
