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.
