  @inproceedings{11239012, abstract = {This paper presents a two-stage power electronics system to control a DC-arc-plasma torch. The first stage is realized by a PFC module consisting of a two-level inverter topology. Due to the requirement of the plasma torch's anode to be connected to potential earth, a galvanic isolation is mandatory. Hence, the second stage is made up by two interleaved push-pull converters, connected in parallel for higher output currents. This paper discusses the challenges of the control of DC-arc plasma due to its negative differential resistance, causing the closed-loop control to oscillate with the arc plasma.}, author = {Hirning, David and Haarer, Jörg and Eckstein, Mattea and Haspel, André and Kirschner, Marcel and Roth-Stielow, Jörg}, booktitle = {2025 Energy Conversion Congress & Expo Europe (ECCE Europe)}, doi = {10.1109/ECCE-Europe62795.2025.11239012}, month = {09}, pages = {1-6}, title = {PFC and Push-Pull Converter Configuration for a DC-Arc-Plasma Torch}, url = {https://ieeexplore.ieee.org/document/11239012}, year = 2025 }

  @inproceedings{10173451, abstract = {Signal injection is a well-known technique to identify the actual rotor position of an AC machine in lowspeed and standstill using the saliency of the machine. It enables a field-oriented control without a position sensor. This paper discusses the disturbing influence of magnetic cross-saturation on the estimated rotor position of an interior permanent magnet synchronous machine and presents two possibilities to compensate the errors caused by this influence. Simulation models are used to demonstrate and analyze the position deviation caused by the saturation effects and to evaluate the effectiveness of the proposed compensation methods. Several measurements on a machine testbench validate the simulation results.}, author = {Haspel, André and Ketchedjian, Vasken and Kirschner, Marcel and Roth-Stielow, Joerg}, booktitle = {PCIM Europe 2023; International Exhibition and Conference for Power Electronics, Intelligent Motion, Renewable Energy and Energy Management}, month = {05}, pages = {1-10}, title = {Impacts of Cross-Saturation on Sensorless Control of Synchronous Machines using Alternating Signal Injection}, url = {https://ieeexplore.ieee.org/document/10173451}, year = 2023 }
