Mobile DRT VLF test system2011 - 2015
Testing of high voltage cable is important to guarantee the reliabilty of electric distribution networks. This project considered the control of a test system, which utilizes high voltage with very low frequency (VLF). A main part of the project was the optimization of the system parameters in order to improve the overall closed loop behavior. The practical feasibility of the control and estimation strategies was proven by means of measurements on the real test system. Read more →
Nonlinear control and protection concepts for Smart Power ICs
Smart Power ICs are Power Switches with integrated control and protection functions for the switching of middle and high current loads in industrial and automotive applications. Due to customer specifications and electromagnetic compatibility requirements it is often desired to limit the current and voltage slew rate at the output terminal of Smart power ICs by minimizing the switching losses at the same time.
