| 14:00 | Operating performance of Modular Multilevel Converters in drive applications Johannes Kolb, Felix Kammerer, Michael Braun, Karlsruhe Institute of Technology (KIT), D The Modular Multilevel Converter (MMC) is an upcoming topology for high power drive applications in the medium voltage range. This paper presents the investigation of MMCs used as motor-sided converter as well as grid-sided active-front-end converter. Experimental results from a prototype system show the operating performance of the DC-coupled MMCs at steady state. The dynamic response of the system is tested to verify the cascaded and transformed control scheme of the MMC. |   | ||
| 14:30 | Cost-effective implementations of sensorless control strategies Giacomo Scelba, A. Consoli, A. Gaeta, G. Scarcella, University of Catania; A. Cucuccio, D. Costanzo, L. Billè, ST Microelectronics, I The main goal of this work is to show how the functionality of a motor drive position estimation technique based on carrier signal injection can be highly improved by adopting novel low-cost microcontrollers to minimize the computation effort and the hardware requirements of the whole control system. A description of the implementation issues and a presentation of some experimental results obtained on a particular HF signal injection sensorless technique are presented. | | ||
| 15:00 | Initial Rotor Position Detection in Electrically Excited Medium Voltage Synchronous Machines Simon Feuersänger, Jose Mario Pacas, University of Siegen, D In inverter fed, encoderless operation of the synchronous machine the rotor or flux position is mandatory. This information is obtained based on the evaluation of the machine voltages. However, until now the rotor position identification at standstill is only possible if the machine exhibits special characteristics and excludes the identification in most SMs. The present paper introduces a novel approach which works properly in a wide range of SMs. | |||
