The book "Electronics in Electrical Complexes and Systems (in Tasks)" edited by the team of authors is a unique educational resource that will be of interest to both students and practitioners in the field of electrical engineering and electronics . This edition is not just a manual, but a whole guide to the complex and fascinating world of electrical systems, which offers readers the opportunity to better understand the principles of operation and application of electronics in various complexes. From the first pages, the authors immerse the reader in the world of electrical systems, starting with the basics and gradually moving to more complex tasks and concepts. The book covers a wide range of topics, including circuitry, electric machine control, and automation and control systems. Each section contains practical tasks that help to consolidate theoretical knowledge and develop skills in solving real problems. This makes the book especially valuable for technical students who are preparing for professional activities, as well as for engineers seeking to improve their qualifications. One of the key features of the book is its practical focus. The authors not only present the theory, but also offer readers a variety of tasks that illustrate the application of the knowledge gained in real conditions. This allows the reader not only to study the material, but also to learn how to apply it in practice, which is an important aspect in the engineering profession. Questions and tasks are diverse: from simple calculations to complex project tasks, which makes the book a universal tool for learning and self-testing. The book will be interesting not only for students and graduate students, but also for practicing engineers who want to update their knowledge or master new technologies. It can also be useful for teachers who are looking for quality teaching materials for their courses. It is important to note that
