If you look through the typical college text on industrial electronics, you will find about two pages of generic descriptions about the SCR. But the diverse applications of the SCR are the mainstay for the precise control of electrical power in most industrial applications. This little gem of a book is the only one I have seen that covers all the basics and much more. While the bare SCR first appears to be a one trick pony, this book describes how the magic in the control circuit can turn it into a multitude of products.
If you market any product related to industrial heating, you will find the extensive list of client industries buying SCR controls a treasure trove of market leads.
If you are still in one of the old-time industries that still spends a small fortune maintaining industrial mechanical contactors, this is the book that can simply explain how you can eliminate that costly maintenance downtime and keep much more profit in your pocket. After the diode, the SCR is one of the most rugged and easy to use semiconductors with massive power handling capability at a low cost.
If you are already using an SCR controller, you probably only know about that one type. As processes change, and the market demands increasing product quality, it can be worth your time to periodically review the variety of available controllers for one that can better meet your needs in changing times. The variety of SCR controllers can be intimidating. This book is the cornucopia of SCR controller knowledge that gives you decision power. This is the book you want in your pocket when the SCR rep visits so that you are an informed consumer that can determine what product can best meet your needs.
If knowledge has value, this book is one of the best bargains you will ever find. If you happen to buy it for a college engineering class, it will be one of your keepers. The author covers a complex subject in a very simple, easy to absorb, writing style that does not bog the reader down.
