The power electronics course focuses the attention of students, who already know most of the possibilities of electronics, on the elimination of losses, introducing switching methods suitable to replace linear operation. The electronic components that they already know are now examined, along with new ones, from another perspective, that of operating as switches. Attention is focused on any disadvantages of switching methods and how to deal with them. Upon successful completion of the course, the student will be able to:

• Know how to design to minimize losses.
• Have knowledge of the effect of the characteristics of the components on the switching function.
• Know how to implement a power electronics device in order for it to operate effectively.
