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.
Your manager has requested you to review current techniques for reducing, or eliminating, the effects of external interference upon electronic circuits. He requires a short report
