Question

If the turns ratio of the primary and tertiary windings of the forward transformer are in the ratio of 1:2, what is the maximum duty ratio at which the converter can be operated? Corresponding to this duty ratio, what should be the minimum ratio of secondary to primary turns if the input dc supply is 400 volts and the required output voltage is 15 volts? Neglect switch and diode conduction voltage drops.

Answer 1
