Power Electronics: Principles of Analysis and Design with Emphasis on Magnetics Volume 1

I soon learnt how to effect piecemeal analysis of non linear circuits. Combing this with my book on swtiching power supplies I am fully confident/competent at designing and building my own specialist power supplies. This is because the commecially available ones do not do what I want to do. So I design from scratch and build to my own specifications.I highly recommend this for a thorough understanding of power supplies and the associated inductors/reactors/transformers used therein.
