The model is mainly based on the loss calculation of the electrical components of the drive train, which is the focus of this paper. Moreover, the torque distribution over the wheels, the power flow through the electrical and electromechanical components, as well as the battery capacity, which are necessary for the design of the drive train, is also discussed. Finally, the different strategies, which are used for the energy management within the drive train and for the control of the converters, are introduced.}, author = {Ketchedjian, Vasken and Haspel, Andre and Schuster, Johannes 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 = {Modeling of the Drive Train and Energy Management Strategy for a Hybrid Midsize Multifunctional Vehicle}, url = {https://ieeexplore.ieee.org/document/10173236}, year = 2023 }

  @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 }

  @inproceedings{10213689, abstract = {This paper proposes a novel controller design for harmonic current control of synchronous machines based on a plant model in a harmonic reference frame. The modeling in the harmonic reference frame exposes additional harmonic couplings in the plant's transfer function, caused by the different inductances in the direct- and quadrature-axis of the rotor. These effects disturb conventional harmonic controllers. Therefore, the proposed controller uses an inverse plant model including the additional harmonic couplings, to achieve the desired stationary and dynamic behavior. The implementation of the novel harmonic controller, simulations and experimental results are presented for a permanent magnet assisted synchronous reluctance machine.}, author = {Haspel, André and Kaiser, Kim and Ketchedjian, Vasken and Roth-Stielow, Jörg}, booktitle = {2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)}, issn = {2150-6086}, month = {05}, pages = {2979-2986}, title = {Harmonic Current Controller Design for Anisotropic Synchronous Machines based on a Machine Model in Harmonic Reference Frame}, url = {https://ieeexplore.ieee.org/document/10213689}, year = 2023 }

  @inproceedings{10264595, abstract = {Characterizing the switching losses of wide bandgap semiconductor devices requires wide bandwidth measurement equipment with the smallest possible insertion inductance added to the commutation path by the current sensor. A common current measurement approach is using low-cost off-the-shelf SMD resistors and measure the voltage drop. This SMD shunt approach has a limited bandwidth due to parasitic inductances. In this work, an evaluation of such a low-cost current shunt is performed. The influences and constraints that limit the bandwidth are investigated. The design of a compensation network and the resulting bandwidth improvement are examined. Based on the theoretical discussion, a compact current shunt is designed, that allows a simple integration into the commutation path while adding a low insertion inductance. The measurement results show, that the common measurement approach can reach a bandwidth of several hundred MHz if the design constraints are met and can be further extended by a compensation network.}, author = {Ziegler, Philipp and Haarer, Jörg and Marx, Philipp and Eckstein, Mattea and Haspel, André and Roth-Stielow, Jörg}, booktitle = {2023 25th European Conference on Power Electronics and Applications (EPE'23 ECCE Europe)}, month = {09}, pages = {1-9}, title = {Evaluation of a Low-Cost Wide Bandwidth Current Shunt for Characterization of Wide Bandgap Semiconductor Devices}, url = {https://ieeexplore.ieee.org/document/10264595}, year = 2023 }

  @inproceedings{10264532, abstract = {To emulate the reaction of an electrical machine interacting with a device-under-test inverter, a power-hardware-in-the-loop emulator has to provide a suitable countervoltage per phase. For the correct emulation of the dynamic electrical behavior of the machine, especially the current ripple, the countervoltage has to include a steady oscillating component and a stepwise changing component. This paper introduces a novel approach to determine the analytically ideal shape of the countervoltage for the emulation of three-phase machines and provides a simulative validation. As example, a synchronous machine operated with a two-level voltage source inverter is regarded. It is shown that the relation between the machine’s direct and quadrature inductances as well as the coupling between the device-under-test inverter and the emulator have a significant influence on the shape of the countervoltage.}, author = {Haspel, André and Ketchedjian, Vasken and Marx, Philipp and Eckstein, Mattea and Roth-Stielow, Jörg}, booktitle = {2023 25th European Conference on Power Electronics and Applications (EPE'23 ECCE Europe)}, month = {09}, pages = {1-10}, title = {Composition of the Countervoltage for Power-Hardware-in-the-Loop Emulators for Three-Phase Machines}, url = {https://ieeexplore.ieee.org/document/10264532}, year = 2023 }

This method requires a minimum number of measurement parameter to determine the MTPV-trajectory without any previous knowledge of the inductances and its saturation effects. The proposed method is an open-loop control which is based on the same principle of measurement as the maximum torque per ampere (MTPA)-trajectory and can be easily implemented on a test bench. The functionality of the open-loop control is first tested using the simulation tool Matlab-Simulink. Then the open-loop control is implemented on an existing test bench to verify its functionality experimentally and compare the obtained simulation results with the measurement results.}, author = {Ketchedjian, Vasken and Haspel, André and Haarer, Jörg and Roth-Stielow, Jörg}, booktitle = {2022 International Power Electronics Conference (IPEC-Himeji 2022- ECCE Asia)}, editor = {IEEE}, month = {05}, pages = {2714-2720}, title = {An Open-Loop Control for the Determination of the MTPV-Trajectory of a SynRM}, url = {https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9806916}, year = 2022 }
