Content


1. Introduction to power systems

2. Rectification AC / DC recharge with diodes

3. Rectification AC / DC with thyristors (phase control)

4. Direct DC / DC conversion with MOS transistors and diodes

5. DC / DC conversion with transformers

6. Power semiconductor devices

7. Design of passive power elements (L, R and C)

8. Thermal management of power systems and aspects related to the encapsulation of passive and active components

9. DC / AC inversion

Methodology


The evaluation of the subject will include:

1. Partial exams (one of rectification and one of conversion and design of inducers)

2. Laboratory practices

3. Individual or small group exercises

Eventually, and depending on the notes given in the three items to evaluate, there may be slight modifications of the weight of each item in the final grade to correct correct possible errors in the difficulty of an exam, etc. It is necessary to pass the 'partial exams. In case of not doing so, a second opportunity will be available at the end of the course.
