    Please help me that how do I determine proper wire size in SMPS for building a ferrite core transformer.

    How much current do you plan on passing through the wire?

    Here's a link to a table of wire sizes and resistances:
    http://www.powerstream.com/Wire_Size.htm

    It's a handy one because in addition to AWG size, diameter, Ohms, and Amperes, it also has frequency limits for 100% skin depth on solid conductors.

    You might want to read through this page:

    It's for low-current high-voltage flyback converters, but there's some good info on using ferrites in winding transformers/inductors for power supplies, and testing them.
