A Flyback converter has an input of 332 V from a DC source, operating at 40 kHz with duty cycle approximately 1/3 The rated output is 12 V at 5 A. The circuit operates with continuous inductor current at threshold 1.5 A, and the turn ratio must be an integer. By assuming that all the components are ideal, and capacitor and inductor are operating in steady state: i. Draw the converter circuit. Determine the inductor's turn ratio. Determine the primary inductance. iv Sketch the diode current and switch current. V. Find the peak and mean of the switch current.

be an integer. By assuming that all the components are ideal, and capacitor and
inductor are operating in steady state:
i.
Draw the converter circuit.
ii.
Determine the inductor's turn ratio.
iii.
Determine the primary inductance.
Sketch the diode current and switch current.
iv
V.
Find the peak and mean of the switch current.
