If you tell us what you are trying to do we can help, but your previous posts and this one are just far too vague.

Are we talking DC/DC converter in a cell phone or perhaps a DC/DC converter for a multi GW DC transmission link? Who knows? Does MISO mean something (an acronym perhaps), to me it is just a seasoning?

What's the application, what power level and voltage? Is this for a new product or school project or general interest?

The more information you provide the better we can answer your question.

Actually I am doing my bechlor in electronics. And my final year project is "TO DESIGN A MULTI INPUT SINGLE OUTPUT POWER EFFICIENT DC-DC CONVERTER" for that I am collecting information .

You guys are very helpful. Thank you for giving me your time

Ok that narrows it down, but what size DC-DC converter? You can get DC-DC converters in chip form now days and there are thousands of designs available online from DC-DC controller manufacturers.

For a Bachelor-level project I would expect something quite special, effectively designing, modelling and producing an efficient DC-DC converter circuit from scratch without the standard DC-DC control chip that does all the work nowdays.

There are vast, VAST quantities of design data available online and through major chip manufacturer websites, all for free. From chip design level up to large scale DC-DC converters. So much in fact I gave up reading and storing it for later use and just use an internet search engine to find what I want.

You need to perform an internet search starting with the basics first and then narrow down the scope of your project to something you can manage and are happy attempting otherwise your project will be to broad and basic (just repeating what is already available on line) or to complex and unachievable.

You're welcome. Good luck!

Put some numbers down!

<...MISO...> most likely means Multi Input Single Output in this case, by context and pattern recognition. However there are currently 26 other possible meanings at http://www.acronymfinder.com/MISO.html, which have been discounted here.

You already have much of the information you need by simply following the links provided by others in your previous posting. Google is your friend for seeing how others have solved the same problem.
