i have to design fly back buck converter circuit , which gives the output of 16v,12v,24v with 3 amps(all are separate).the input details is 95v-245v AC , 50/60hz.
in the buck converter , my main motto is to eliminate the primary transformer. so that i selected the rectification parts in 245v/1A level. actually i had finished the MOSFET selection also.
my problem is in the selection process of inductance. wh are the points to be considered in inductor selection?
i dont have any idea about the switching frequency related to inductance.
can any one help me to finish the buck converter circuit?
As you said 16x3 + 12x3 + 24x3 = 156W, the converter should not be a small one or less weight. Please specify the actual requirement (Comfortable) .
1 Select high efferent low profile transformer.
2 Operating frequency increase as possible…ect .

in the above figure ,it showed three different output voltages. but basically, three different buck converter. hopefully ,now you can understand my requirement.
