Loop Control for Linear and Switching | |||||||||
| |||||||||
oop control is an important topic to the student and the electronics engineer. The theory can be extremely complex and encompasses a lot of different fields: electronics, mechanics and fluid mechanics to cite a few. Most of the available theory books often attempt to cover the subject exhaustively; quickly drowning the readers into a sea of mathematical details they will never use or are irrelevant to their professional field. Furthermore, these textbooks remain highly theoretical and the link to practical applications is often overlooked. Trying to apply what has been learned to a real case quickly ends up in a dead-end: equations or descriptions simply do not match the environment the engineer is confronted with.
This new book published by Artech House Publisher “Designing Control Loops for Linear and Switching Power Supplies: a Tutorial Guide”, explores a different path. Christophe Basso, the author, purposely narrows down the field to what power electronics engineers really need to know for compensating or stabilizing the system they are working on. The book not only builds the necessary theoretical foundations but also clearly shows how to apply what is analytically explored to practical cases. For this reason, this book will not only please the practicing engineer but also appeal to students looking for a link between theory classes and their future work. For example the TL431 is a complex device and its implementation in compensation stage is often overlooked, especially if an optocoupler is added in the chain. In his new book Christophe Basso dedicates an entire 70-page chapter to the TL431, detailing internals of this popular component. The book reviews the three compensation types (1, 2 and 3) for isolated and non-isolated converters built around the 3-leg self-contained reference voltage op amp. The book also explores in details other compensation structures made with op amps but also transconductance amplifiers and popular shunt regulators.
The author, Christophe Basso, is an Application Engineering Director at ON Semiconductor, in France. SPICE simulation is one of his favorite subjects and he authored two books on the subject. In his work, he promotes the combined usage of SPICE as a design companion which, associated to an equation-based approach, helps to understand how complex circuitries operate. Developing new integrated circuits but also helping and teaching design engineers is part of his professional activity in the field of ac-dc power conversion for the last 15 years. Christophe maintains a webpage where documents and models are available for download: http://cbasso.pagesperso-orange.fr/Spice.htm. A complete description of the book content and documents pertaining to switching power supplies is available on the author’s website at: http://cbasso.pagesperso-orange.fr/Spice.htm
