General information about the course
The use of fast-switching power transistors such as silicon carbide (SiC) MOSFETs and gallium nitride (GaN) HEMTs poses new challenges for measurement technology and methodology. Fast current and voltage slopes, high switching frequencies and voltages make precise measurement of the power transistors difficult. In this master lab course, the theoretical principles of measurement technology are teached and applied using various application-oriented measurement methods.
The measurement techniques taught include:
- high bandwidth current measurement
- high bandwidth voltage measurement
- measurement of the switching losses of power transistors in the electrical domain using the double-pulse test
- high bandwidth temperature measurement and calorimetric switching loss measurement
Current information for interested students
The practical course is offered in the summer semester. The next date is therefore the summer semester 2025. The number of participants is limited to 8-10 persons due to space restrictions.
IMPORTANT INFORMATION - The lab course "Dynamic and application-related measurement techniques for fast switching power transistors" will be offered as on-site course with physical presence of students on the premises of ILH. The lecturer reserves the right to change the mode of organization in order to comply with the prevailing frame conditions for on-site courses.

| Objective |
The objective of the lab course "Dynamic and application-related measurement techniques for fast switching power transistors" is to impart knowledge on measurement methods as they are used in current industrial and university research to measure switching processes in fast switching power transistors. The students learn how to safely use measuring devices, how to use different probes and how the measurement results are to be interpreted after weighing different influencing parameters. |

| Organization |
There will be an information event on the lab course on Thursday, 11 April, 2024 at 11:30 am. The subjects of the experiments are explained and organizational questions answered. An email as information will be sent in advance to all students who have registered for the lab course in the C@MPUS system of the University of Stuttgart. After a laboratory safety briefing, there will be a theory unit on wide-bandgap power transistors. The practical experiments are then carried out every two weeks. Each experiment consists of the preparation of the experiment, the implementation of the experiment and the interpretation and evaluation of the measurement results obtained. All relevant measurement results of the tests are to be summarized in documentation and then presented in the form of a short presentation. Further organizational information will be announced in the ILIAS course of the lab course. |
