Power electronics - a specific area of knowledge engineering, where a lot is determined not so much a purely theoretical knowledge as experience, erudition, lively search for ways to design reliable electronic equipment. Ways of solving a technical problem of power electronics can be quite unconventional, although there are a number of rules, without observing that if nothing is impossible to develop workable.
This book is designed to help get involved in the design, construction and operation of static converters of electricity on the basis of modern semiconductor power components. The book is addressed to engineers and technicians engaged in the development, modernization and repair of power electronics, and students of higher secondary schools, as well as anyone interested in the problems of converters.
