IH2661 Power Semiconductor Devices 7.5 credits

The course deals with the operation of power semiconductor devices from basic physical models and transport properties, but the focus is on the understanding of different device concepts. The operation of bipolar power devices, as pin-diodes and various types of thyristors are described, but also the principles for unipolar rectifiers and switches such as power MOSFET is included. Modern devices often make use of a combination of unipolar control and bipolar power handling and the course also describes these devices, for instance the IGBT and MCT structures. Also devices made of semiconductors other than silicon, i.e., silicon carbide, will be addressed.

The objective is to understand the operation of power semiconductor devices, and advantages and disadvantages with various materials and device concepts, so that a suitable device can be selected for a particular application.

Compendium

If the course is discontinued, students may request to be examined during the following two academic years.

• ANN1 - Project Work, 7.5 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

No written examination will be given, but instead the students are required to fulfill a smaller project and present their results and hand in solutions to selected problems.
