        Modern converter drives

        drive systems, power electronics, machines, mechatronics ans motion control

        by Peter F. Brosch

        Increased automation requires variable-speed drives. Various types of converter can function as actuators together with all kinds of machines. This book provides an overview of the various possibilities. It is addressed both to students who are as yet unfamiliar with the subject as well as to practitioners wanting information on the state-of-the-art of variable-speed drives.

        KNX/EIB Engineering Tool Software

        Safe Installation and Changeover from ETS5 to ETS6

        by Michael Körmer, Willi Meyer

        Smart home solutions are in vogue, but require precise knowledge of the underlying hardware and software. Those who do not deal with ETS programming on a daily basis sometimes find it difficult. Instead of relying on memory and colleagues' knowledge for setup, this book helps as a step-by-step guide: the overall process of programming and commissioning KNX/EIB projects based on the current Engineering Tool Software (ETS) is covered. This enables you to follow all the necessary steps before, during and after processing with ETS5 and ETS6 "in one piece". The book takes into account the current state of the software based on ETS5 as well as ETS6. From the determination of requirements to the documentation, the necessary knowledge is conveyed. All actions with the discussed software tools are illustrated by screenshot, which ensures a good comprehensibility. For practical understanding, the complete project of a single-family house is also presented step-by-step and richly illustrated. This book will help you especially with the following questions: What are the basics of KNX hardware and software? What basic knowledge do I need specifically for ETS5 and ETS 6? What are the differences and similarities between the two KNX tools? How do I lead an extensive KNX project to success? (Practical example)

        Building Biology Measurement on EMF

        Basics of Field Theory, Practice of Field Measurement Techniques

        by Martin H. Virnich

        The teaching of well-founded, practice-oriented EM field measurement technology on a scientific basis is the central concern of Dr.-Ing. Martin H. Virnich's book. In an easily understandable form and without "higher" mathematics, the author clearly presents the fundamentals of field theory in a depth necessary for practice. Core topics of his book are the following aspects: Physics of EM fields, Measurement of vector fields, Alternating electric fields (low frequency and DC fields), Alternating magnetic fields (low frequency and DC fields), Electromagnetic waves (high frequency), "Dirty Power", as well as The alteration of the natural EMF spectrum and its consequences. New to this 2nd edition is a detailed section on 5G NR, which deals with the current mobile communications standard and its many manifestations. In doing so, it dispels a number of myths surrounding 5G.
