Eletrónica de Potência

Knowledge of electronics

Knowledge of circuit analysis Application

Knowledge related to Fourrier series

Knowledge of control systems

Por necessidade de alterar o método de ensino, pois neste ano lectivo, no Regime Pós-Laboral já não existiram aulas neste horário, os alunos poderão fazer a UC apenas por exame, sendo considerada a nota de laboratório de anos anteriores. Os alunos estão sujeitos também à entrega de um trabalho de simulação.

Power electronics systems deal with the process of converting electrical power from one form to another. The syllabus reflects the learning objectives of curricular unit. The main learning objective of this curricular unit is to provide students with technical knowledge about energy conversion based on power electronics converters, including an understanding of the main conversion topologies, their operating principle and their applications, as well as of design and control. Students should acquire the necessary skills to simulate and study the classical converters under analysis, as well as be able to implement the same converters in a laboratory environment. With the knowledge provided in this curricular unit, the students will be able to have an integrated view of power generation and conversion systems, particularly from the power electronics point of view.

1. Overview of Power Electronics Devices : Seminconductor Devices and Passive Components: Conversion chains and applications.

 2. AC-DC Converters: 2.1. Non-controlled rectifiers (diodes). 2.2. Semi-controlled and full-controlled rectifiers (diodes and thyristors). 2.3. Line-current harmonic distortion and input power factor in nonlinear loads.

 3. DC-DC Converters: 3.1. Introduction, technologies, power topologies and power levels 3.2 Non-isolated topologies 3.3 Isolated topologies.

 4. DC-AC Converters: 4.1. Half-bridge and Full-bridge single-phase Inverter 4.2. Modulation strategies 4.3. Full-bridge three-phase, two and multi-level Inverters

 5. Applications and Power converter modelling, simulation and control basics.

Written exam in addition to previous years lab grade + simulation assignement

Anulled:

Written Exam: 12/20 points
Passing Requirement: Minimum 50% average
Laboratory work 8/20: two individual tests in class and one group assignment based on simulation with report and oral presentation.
The tests (worth 3 points) on the knowledge acquired in the practical classes will be carried out during the laboratory sessions with prior notice.
The oral presentation will take place during the support week.
Attendance at experimental practical classes is mandatory, according to the schedule agreed with the students.
If students do not obtain a grade higher than 3 points in the laboratory component, they will not meet the requirements to sit the final exam.
Only the grade for the final exam component can be improved.

Note: For students with the Student Worker Statute (Law no. 99/2003 and Law no. 35/2004), with regard to the components with mandatory attendance and distributed assessment, it may be agreed between the person responsible for the curricular unit and the student, on his/her own initiative, an alternative way of operating these components. In this case, during the first two academic weeks, students must indicate to the respective teacher their status as student worker, establishing from the outset the form of evaluation of the practical component. It may be required to present the work schedule authenticated by the employer.
