Calculate turns ratio, Electrical Engineering

A switch-mode power supply is to be designed with the following specifications: input voltage Vs = 48 V ± 10%, output voltage Vo = 5 V, switching frequency fs = 100 kHz, output power Po = 15-50 W. A forward converter operating in a continuous current mode with a demagnetizing winding of N3 = N1 is to be used. Assume all components to be ideal except for the presence of the transformer magnetization inductance.

(a)  Calculate N2/N1 if this turns ratio is desired to be as small as possible.

(b)  Calculate the minimum value of the filter inductance.
