This paper describes the design and analysis of a SiC-based Active-Front-End with a switching frequency of 100 kHz and an output power of 50 kW. The focus of this Active-Front-End is on the small input inductance (uk=0,6%), which has been deliberately reduced in order to reduce package size. For a small inductance a high switching frequency and a fast and precise current measurement are basic requirements. The increase of the switching frequency reduces the size of the whole filter.}}, author = {{Otte, Raphael and Koch, Jan-Niklas and Borcherding, Holger and Stuckmann, Tim}}, booktitle = {{PCIM Europe : International Exhibition and Conference for Power Electronics, Intelligent Motion, Renewable Energy and Energy Management, 11-13 June 2024, Nuremberg}}, isbn = {{978-3-8007-6262-0}}, keywords = {{DC-Industry, DC-Grids, AIC, AFE, Active-Infeed-Converter, Active-Front-End}}, location = {{Nürnberg}}, pages = {{3402}}, publisher = {{VDE Verlag}}, title = {{{Design and Analysis of a 50kW SiC-based Active-Front-End with a very small line choke for DC-Grids}}}, year = {{2024}}, } @misc{4918, abstract = {{An open industrial DC grid has a lot of advantages.

The reduction of energy consumption results from the interaction of optimized components (motors, control techniques and regeneration units), which are described in detail in this paper. Different motor concepts like the induction motor, the synchronous reluctance motor and the permanent magnet synchronous machine are compared according to the special requirements for intralogistics applications. Different control techniques are presented in order to achieve sensorless and efficient-optimal operation of these motors. The sensorless control technique uses signal injection to detect the rotor position sufficiently exact also in case of speed near standstill. Efficient-optimal operation is achieved by reducing the motor current with regard to the torque (MTPA-control). Furthermore this paper introduces a regeneration unit that can be connected between the DC link of frequency inverters and the mains to feed back regenerative energy. The regeneration unit consisting of a buck converter, a synchronous inverter and a line-filter can work in parallel to commonly used uncontrolled rectifiers. Its functioning is shown with the help of measurement results of a 1kW laboratory prototype. The last section shows a demonstrator in which a conventional conveyer system (with induction motor and braking resistor) is compared with an optimized one using the presented components. Power versus time measurements show specific energy savings resulting from the interaction of the optimized components.}}, author = {{Austermann, Johann and Borcherding, Holger and Stichweh, H. and Grabs, Volker}}, booktitle = {{2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe)}}, isbn = {{978-3-8007-4186-1}}, keywords = {{electric current control, induction motors, invertors, permanent magnet motors, reluctance motors, sensorless machine control, torque control, modular solution kit, intralogistic drives, automated warehouse, energy consumption reduction, optimized components interaction, induction motor, synchronous reluctance motor, permanent magnet synchronous machine, sensorless control technique, signal injection, rotor position, motor current, MTPA-control, regeneration unit, DC link, frequency inverters, buck converter, synchronous inverter, line-filter, Induction motors, Reluctance motors, Permanent magnet motors, Rotors, Torque, Inverters, intralogistics, reluctance motor, sensorless control, regeneration unit, braking energy}}, location = {{Karlsruhe}}, pages = {{1639--1646}}, publisher = {{VDE Verlag}}, title = {{{High Efficient Modular Drive System - An Ideal Approach for Green Intralogistics Applications}}}, doi = {{10.1109/EPE.2016.7695687}}, year = {{2016}}, } @inproceedings{4818, abstract = {{In this paper we present a system that provides personalized privacy support for large public displays based on the current social situation and individual privacy profiles.
