I wanted that answear to come from @hamedyas, at least i would have known he does have some understanding of switching PSU's...The lack of any response to my questions cind of makes me think he really doesn't know much of anything... hope i'm wrong...At 1000w the flyback SMPS would be out...
At 1000w the flyback SMPS would be out, they are only good upto about 300w.
All of that sounds good ( maybe even hi-end ) as an config but you have to take into account the thread author's experiance in developing souch units ( switching PSU ), what you propose needs a good knowledge and understanding of the switching technology, it is not something for the begginers, and although i cannot possibly know if @hamedyas is a begginer ( i appologise if it seams like an offence, i give you my word it isn't ), but i think he is not verry experianced designer otherwise he would have came up with a much more elaborated first posting, at least some basic design witch only would need some improoving, but giving only so little and asking for so much has to say something. What is my point? well, i think it should be kept simple, as simple as the requirements allows, loose the PFC ( witch adds to complexity and cost ), loose the syncronus rectifyer witch also adds to complexity and cost, half bridge to keep the drive section simple and easy to get good parts ( power switchers mainly ), voltage mode control for good transient response and load/line regulation ( granted compensation might get tough but it can be done easily enough ), and if the load powered by it does not protest a simple overload/short protection witch will block the unit at the desired threshold.Personally I'd use the following architecture:..
i want to design smps about 1000w output (100volt ,10amp)
any one can help?
