Static Electromagnetic Frequency Changers is about the theory, design, construction, and applications of static electromagnetic frequency changers, devices that used for multiplication or division of alternating current frequency. It is originally published in the Russian language. This book is organized into five chapters. The first three chapters introduce the readers to the principles of operation, the construction, and the potential applications of static electromagnetic frequency changers and to the principles of their design. The two concluding chapters use some hitherto unpublished work of the author and provide examples of the design of frequency doublers and triplers. This book will be of interest to engineers and scientific workers, engaged in the field of automatic control electrical machines and in other fields of technology connected with the use of alternating current above normal supply frequencies.
