    Hi Chirag,

    Welcome to element 14. I have been watching your post to see if anyone would try to answer you. I have a few questions for you. Why are you designing this power supply as opposed to looking for an existing supply? What have you done to this point to effect a design? Do you have some specific questions related to your design process? The design of a power supply like this is a complicated time consuming process and most people are going to be reluctant to get involved in it without a better understanding of the whole picture. I hope we can get some dialog going here for you. Once again welcome to the forum. I look forward to getting to know you better going forward.
