My first introduction with

**“Transformer and Inductor Design Handbook”**is at the time when I started my career as Design & Development Engineer after graduation with a well-known organisation. There we use transformers and inductors in our designs. To understand the ferrite, transformers and inductors well, my seniors suggested to refer this book. He has one copy and initially I referred his copy.
When I read this first time, I
found that this book contains all the detail explanations of ferrite selection,
transformer & Inductor calculations and their working. It offers what you
have to work with ferrite parts. It delivers and clears all the basics so that
you can simply use this information when needed. Immediately I planned to
purchase my own personal copy. At that time, 3rd edition was available. Till now
this book is available with me and till now I am referring it for transformer
design and inductor design.

With the time

**“Transformer and Inductor Design Handbook”**flourished and now available in 4th edition, updated and revised by author Colonel Wm. T. McLyman. Because of introduction of new chapters I purchased the 4th edition also.
A new chapter on Autotransformer
Design has been included in 4th edition, which focuses on selection
and calculations of windings. A chapter on Common Mode Inductor Design has been
included which focuses on the selection of ferrite material, winding
calculations, cut-off frequency calculations, temperature rise calculations,
etc.

The book;

**“Transformer and Inductor Design Handbook”**delivers you, step wise teachings along with reference pictures to clear all the concepts of transformer design and inductor design. This book guides you also on topics like; laminations & its need, tape cores, powder cores & ferrite cores, and iron alloys. This book will guide you for; how to select the right ferrite core size for your design, how to perform calculations, how to design transformer and design inductor and how to perform testing. This book will give you transformer design examples along with step-by-step directions and several tables and visuals for assessment.####
