Tutorial Flyback DC converter coupled inductor theory

Flyback transformer design. A flyback converter operates with a 160 Vdc input and produces a 28 Vdc output. The maximum load current is 2 A. The transformer turns ratio is 8:1. The switching frequency is 100 kHz. The converter should be designed to operate in the discontinuous conduction mode at all load currents. The total copper loss should be less than 0.75 W. (a) Choose the value of transformer magnetizing inductance such that, at maximum load current, the duty cycle of subinterval 3, in whi
