About the book

Is  it  is  possible  today  to  design and make automatic devices for industrial  and  power  engineering  uses  without  microcircuits  and microprocessors,  without  complex  power  supplies  for  them? “Yes!” asserts the author of the book, Dr. Vladimir Gurevich, and as proof of this  assertion  provides  descriptions  of tens of original automatic devices  based on modern discrete components: high-voltage transistors and  thyristors,  miniature  vacuum  and  high  power  gas  filed reed switches,  and  combinations of them. Such devices turn out to be much more simple and, in many cases, more reliable than the traditional devices made today.  To make the material more accessible to a broad spectrum of readers, the author begins the book with an explanation of the working principles of semi-conductor devices of various types and, further, through the description of elementary functional modules, passes on to complete automatic devices.  The book finishes with extensive reference material on modern high-voltage bipolar, FET and IGBT transistors, thyristors and triacs, reed switches, especially selected by the author.
