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.
#ques1. (MATLAB) Generate 100 samples of the signal = sin (0.125). We want to decimate this signal using D = 2. • Design a 25-order lowpass filter using the Parks-McClella
