Simulating Switching Converters with LTspice

Simulating Switching Converters with LTspice, describes numerous simulation templates of switching converters, all running with the free simulation program originally released by Linear Technology, later acquired by Analog Devices, Inc (ADI).

All the examples proposed by Christophe Basso, cover a vast range of applications and are carefully crafted, including, for most of them, the design of the control loop which is an essential part of the design. The circuits are controlled by generic controllers which operate in various operating modes as the below short table of content describes:

And many more examples with PFC and UC384x circuits

You will learn how to assemble a generic transformer featuring two or more windings, drastically simplifying simulation and making parasitics visible; what a coupling factor naturally hides. For first-order simulations, a simple operational amplifier featuring an output voltage clamp with programmable open-loop gain and a low-frequency pole, is all you need to test your loop design: run a first low-level simulation then complicate your circuit with more comprehensive models supplied by semiconductors manufacturers.

All of the examples I documented can be freely downloaded from my webpage and all of them have been tested with the latest LTspice version. Once the package is installed, you are all set to start simulating your converter!

This book is an ideal companion for graduate and seasoned engineers but also for field application engineers (FAEs), willing to understand the topic of switching converter and rescue their customers in design distress.
