For over 20 years, LTspice IV is undoubtedly the fastest software, the most robust and most comprehensive of the electronic SPICE simulators. Unfortunately, the electronic Help file is the only documentation available. It is incomplete and far behind the development of the software; many commands are barely documented, although they are essential, and some do not even appear!
This book was designed to fill this gap. It is much more than a manual because it is enriched with a large number of tips, methods and examples, illustrated with nearly five hundred drawings, diagrams and screenshots. It will help you become a specialist of LTspice IV in a few hours, and a real expert in a few days!
The power of LTspice IV knows no boundaries: The numbers of nodes, components and simulations, the graphics resolution and the size of schematics have no limit other than the power or memory of your PC! Although LTspice IV is the only completely free professional simulator, unlike its competitors, it is uncompromising and unlimited.
This book will be useful for everyone, from the beginner to the engineer tasked with the design of large circuits. Advanced users can start reading from Chapter 4; the beginner should start with Chapter 2 which explores the many files supplied during the installation of LTspice IV. The novice user can then focus on the application developed in Chapter 3. It demonstrates the main operation principles of LTspice IV. The first chapter, describing the genesis of LTspice IV, may be read at a later stage.
The five main editors of LTspice IV are explained in chapters 4 to 8. This is where the explanation of the running of the software begins. Then, all definitions and commands (called simulation directives) are detailed and illustrated by examples in chapters 9 to 11. Chapter 12 deals with downloading SPICE models and subcircuits as well as generating symbols to use them easily. Sources, passive, active and special components and their configuration are described in chapters 13 to 16. Chapter 17 deals specifically with inductors and transformers which have, in LTspice IV, a nonlinear model with extended applications (taking into account the saturation and hysteresis). Chapter 18 focuses on the control panel, a real dashboard where all LTspice IV settings can be found. Chapter 19 is a collection of examples concerning various fields of electronics. This is followed by chapter 20 which answers the most frequently asked questions during the training sessions provided by this author of this book.
Whatever your field of application of electronics, this book will allow you to quickly reach a level of expertise in the field of electronics simulation. It will be a valuable assistance thanks to the very significant time savings it provides. Thanks to this book and LTspice IV you can configure your projects quickly and efficiently. You will understand how you can, with LTspice IV, carry out tests impossible to do with a prototype (temperature excursion, operating at the limits, destructive testing, Monte Carlo analysis, etc.). When you have an idea for an electronic circuit, you will get immediate feedback for its validity using this book and LTspice IV.
LTspice IV does not replace the knowledge you need to design electronic circuits; it makes this task more efficient and faster, thanks particularly to the rigorous approach and the possibility to validate your design immediately. It undeniably helps businesses to save time and money, and substantially improves circuit performance. More and more technical schools, universities and engineering schools offer their students training sessions for electronic simulation with LTspice IV. To completely master LTspice IV and be really efficient with all its commands takes several days of practice. Clear and complete documentation is also necessary, and this is the contribution of this book. Thus, LTspice IV will quickly become your most efficient and precious design tool!
