Q4. A switch-mode power supply is to be designed with the following specifications: Va = 47 V + 10% Vo= 5 V Switching freq. f, = 100 kHz Pload = 15 – 45 W A forward converter operating in a continuous-conduction mode with a demagnetizing winding (N3=N1) is chosen. Assume all components to be ideal except for the presence of transformer magnetization inductance. a. Calculate N2/N¡ if this turns ratio is desired to be as small as possible. b. Calculate the minimum value of the filter inductance.
