A flyback SMPS has been designed with a primary inductance of
20 μH and secondary inductance of 100 μH. It was
specified to operate with an input voltage of
24V, with duty cycle up to 40% and a switching frequency of
25kHz.


Determine the minimum voltage ratings of the MOSFETs that can
safely be used to meet the above specifications using the single-
switched and double-switched flyback converters. Clearly state any
relevant implications, justifications and assumptions.
Calculate the power throughput that can
be achieved at maximum duty cycle.
