Objectives

At the end of the discipline the students must be capable of:
– Use engineering science knowledge to formulate, solve and discuss problems related to Power Electronics conversion
– Use learned technologies in the design of solutions to Power Electronics problems
– Identify and formulate problems in Power Electronics
– Identify requirements for a Power Electronics based system, define functions and architectures and manage a project
– Correctly use the acquired knowledge in the design of a Power Electronics based system, single or multi-disciplinary
– Select and model solutions; simulate, qualitative and quantitavely analyze, and recommend them for a particular application
– Formulate hypothesis, search alternative solutions, propose a solution for a Power Electronics problem and validate it
– Design Power Electronics based energy conversion systems
– Design the implementation process, in its hardware and software components
– Experimentally test, verify, validate and certify a solution
– Effectively work in group
– Making written and oral presentations

Teaching methods and learning activities

The theoretical classes are tutorials with discussion of applied examples.
The practical classes are of three types:
- Home work discussion
- Accompanying the execution of the simulation and experimental works
- Demonstration of industrial equipment
The practical works must be presented in a dedicated oral session
Autonomous work with the software:
- PSIM
- SPICE
- Matlab/Simulink/Power Systems Blockset

Software

PSIM
The Mathworks - Matlab - Release 11.1
SPICE

Eligibility for exams

Not exceed the legal limit of faults and obtain a minimum of 40% in the practical work

Calculation formula of final grade

Evaluation components:
1. Simulation work (S)
2. Experimental work (E)
3. Exam (EX), without notes, with duration of 2h; in English.

Final classification (F):
F=0.15*S+0.35*E+0.5*EX

Course approval requires a minimum of 40% in the exam.

Examinations or Special Assignments

None.
Simulation and experimental works can be done outside the course schedule.
Practical works are mandatory for all course students.

Special assessment (TE, DA, ...)

Special students without practical classes’ presence must do a final practical examination.

Classification improvement

Any part (practical or exam) can be improved, in the established dates. The simulation work can’t be improved.
