A fly-back converter operates in discontinuous conduction mode with fixed ON duration of
the switch in each switching cycle. Assuming input voltage and the resistive load at the
output to remain constant, how will the output voltage change with change in switching
frequency? (Assume discontinuous conduction through out and neglect circuit losses.)
(a) Output voltage varies directly with switching frequency.
(b) Output voltage varies inversely with switching frequency.
(c) Output voltage varies directly with square root of switching frequency.
(d) Output voltage is independent of switching frequency.
