Details |
Due to the expected number of participants, the summary examination is planned to take the form of a written examination, in individual cases also a structured oral examination. The exam ensures that each student has reached the L.O. goals individually. 80% of this summary examination is included in the overall grade. The remaining 20% weighting is based on a lab. |

Minimum standard | Clean separation of mean values, effective values and time-transient signals. Clean handling of the component equations of passive components for time-transient signals. Understanding of the switched character of the electronics (when which semiconductor conducts), and why switching takes place (->energy efficiency). |
Exam Type | EN Klausur |
Goal type | Description |
---|---|
Knowledge | Basics (components, pulse-width modulation, signal description, steady-state analysis, network perturbations) Forced-commutated DC-DC converters (buck converter, boost converter, buck-boost converter, two-quadrant converter, H4 bridge as DC-DC converter) Forced-commutated inverters and rectifiers (H4 bridge as DC-AC converter, three-phase pulse inverter) Outlook: Thyristor-based power electronics |
Skills | The student has a fundamental judgment as to whether or not power electronics should be used for a particular technical application. The student is aware of the importance of power electronics for automation, energy technology and energy efficiency. The students know how the most important converters work. They are familiar with the terms used to describe and characterise power electronic circuits. The student can analyse and discuss concrete power electronic circuits with regard to efficiency, feedback effects and component costs. The series of toolbox topics necessary for the lecture (THD calculation, semiconductor devices, ...) can be fully applied by the student. |

Details | 1. partial mark: entrance certificate. The student is asked to what extent he/she is prepared and has understood the contents to such an extent that participation makes sense. Good contributions, including good questions, are also assessed. 2nd sub-rating: During the internship the supervisors ask various questions, but especially: "What are you doing right now? The answer goes into the evaluation. 3rd sub-rating: After the internship, an elaboration is prepared and assessed. The interview and the observation of the internship is regarded as an essential form to recognize the competence of the students. |
Minimum standard | The students show that they have prepared themselves, that they have understood in advance what the subject of the internship is and that they are actively involved in the internship. |
