This project is about applications of power electronics with pic microcontrollers from a practical view point each project developed in this work have a big importance for every student with interest in this branch of the engineering. Through each project is obtained a clear knowledge about of programmation on pic microcontrollers with the only finality of every person can understand that is possible to develop power electronics with pic microcontrollers and of a way to contribute with the expansion of the programmation on pic microcontrollers in this area. We are realized various examples like velocity control of a single-phase motor, starter of single-phase motor, single-phase rectifier and single-phase inverter. This work focuses on the application of pic microcontrollers in the ample world of the power electronics from a practical view. Each one of the examples in this book is given with its complete source code in embedded C language.
