Description

The practical course is intended as a supplement to the lecture "Components of Micro- and Power Electronics" and therefore deals with the characterization of selected, typical semiconductor components of power electronics, microelectronics and sensor technology. By means of experiments, their operating behavior is to be investigated, and the measured characteristics are to be interpreted. The aim is to gain in-depth knowledge of the structure, functionality and underlying physical processes inside the components. The following component types, among others, are being investigated: • Power MOSFET • IGBT • pin diodes • massflow sensors • solar cells The lab course includes several measurement experiments which are carried out on separate measuring stations. Among others, measurements are performed on forward and reverse characteristics (quasistatic and pulsed) as a function of device temperature, on switching behavior when switching inductive loads, on the thermally safe operating area (T-SOA) of power devices, and on mass flow sensing by means of electrothermal hot-wire anemometry. In addition, an open source semiconductor device simulator is used to investigate the effects of technological parameters on the operating behavior of some devices and the processes inside them.

Prerequisites

Fundamentals in semconductor physics and devices Fundamentals in circuit theory and measurement and sensor technology The content of the lab is corresponding with the lecture "Components in Micro- and Powerelectronics" (EI70720). Hence, the knowledge of the learning outcomes of this lecture are desirable and help. Necessary: Content of the provided lab documents

Teaching and learning methods

Practical, self-directed performance of measurement tasks and execution of simulations. All measurement and simulation tasks are carried out under supervision in groups of two. A script handed out during the practical course serves as preparation and enablesself-organizes working.
