The paper presents in detail a complete real-time model of an urban utility electric vehicle (EV) supplied from super-capacitors validated with hardware in the loop testing (HiL). The real-time model is designed using Typhoon HiL software and ran on a 402 device. The model contains the electrical machine, the mechanical assemblies, the supercapacitors model with its buck-boost converter and additionally, a charging station. Using Energetic Macroscopic Representation (EMR), the simulation program is organized in an action-reaction philosophy based on dedicated pictograms. To perform realistic testing, an urban drive cycle recorded in Cluj Napoca, Romania was used. The EV is supplied by a supercapacitor bank and powered with a permanent magnet synchronous machine (PMSM). The HiL testing was performed only for the PMSM, while the rest of the system remained simulated in real-time. The results proved that the energy consumption drained (during motoring) and supplied (during breaking) by the PMSM superimpose the one obtained from simulations. In doing so, the authors validate the traction part of the model proving the benefits of using only supercapacitors as energy supply unit. Considering the role of such a vehicle, only for urban delivery, its fast recharge can be performed any time the vehicle is parked. This process is also analyzed in the present paper.

An excitation system improving brushless generator performance in a transient state is proposed. Especially, the arrangement is capable of lowering the excitation field current faster than a standard single-quadrant topology. The proposed arrangement is simulated and evaluated with an experimental test setup. The system performance is measured in a steady state operation and with faster load transients. The results indicate that a generator excessive voltage can be effectively limited compared to a case applying standard single-quadrant topology.

The prediction of the vibration behavior is one crucial part of the design process for electric machines. The impact of the winding and the insulation on the stator’s eigenfrequencies, eigenmodes and damping is not sufficiently analyzed. In this paper, the influence of a round wire winding and two different insulation techniques on the vibration behavior is studied. A methodology is presented to compare the measurement results of an experimental modal analysis with the simulation results of an FEM harmonic analysis. The vibration behavior of a blank stator lamination, a stator lamination with an uninsulated winding, an impregnated winding and a potted winding are analyzed. To determine equivalent material parameters for the slot filling, consisting of copper conductors and insulation material, the simulation and measurement results are compared. The Young’s modulus of the slot filling E is identified by performing a parameter fitting. The Sum-Transfer functions, the eigenfrequencies, the damping and the eigenmodes are presented for the measurement and the simulation with the determined equivalent material parameters. The equivalent material parameters can be used for future calculations.

The use of microinverters in photovoltaic systems mitigates the losses produced by the discrepancy between modules. In addition, due to the intermittent nature of photovoltaic energy, the system must have an energy storage system. In the following paper, a hierarchical control strategy based on the feedback linearization control technique and a low-pass filter is proposed for the control of both the PV microinverter and the Hybrid Energy Storage System (HESS) composed of battery and super capacitor, which increase the energy density and power density of the system. In this way, a dynamic energy distribution is achieved, taking full advantage of the physicochemical characteristics of the HESS. Simulated results are presented to validate the suitability of the proposed control strategy.

The presented article deals with a novel power sharing control strategy for converter-based micro-grids. In this regard, a micro-grid fed by two parallel-connected D-Type inverters supplying local loads was used. The configuration of the seven-level single-source D-Type converter with self-voltage balancing capacitors eases the control simplicity as well as integration of low voltage DC renewable energies into the higher voltage micro-grids. However, the control of reactive and active power contributions are the challenges. To address this issue, an anti-windup control strategy is proposed. By applying the proposed control for the proposed multi-cell D-type-based micro-grid, voltage regulation of the point of common coupling (PCC) as well as the power transfer control were sufficiently achieved. For more assurance, both dynamic and steady state operation of the system for sudden changes were investigated via MATLAB simulations.

Current trends in industry indicate that the condition monitoring and fault diagnosis of electric drive systems is becoming increasingly important. Nowadays, highly efficient permanent magnet synchronous motors are among the most often used in these systems. Therefore, the detection of their faults is also becoming a very crucial issue. The most common fault of this type of motor is the stator winding fault. This paper presents the effectiveness of the STFT analysis application of stator phase current signal for the extraction of symptoms from stator inter-turn short-circuits of permanent magnet synchronous motors. The time-based features obtained from the classical FFT analysis are not enough as they do not provide sufficiently unique information of the time of failure and do not allow for the further investigation of its source. The superiority of the proposed detection algorithm over the classical method based on the motor current analysis using FFT is described. The proposed solution is experimentally verified under various motor operating conditions. Additionally, a concept of a diagnostic system for on-line stator winding condition monitoring is proposed.

The voltage stress of inverter-fed electrical machines increases when fast-switching wide-bandgap semiconductors are used. For the design of reliable electrical machines, it is therefore becoming increasingly important to analyze these voltage stresses in the winding system in more detail in order to design a correspondingly robust insulation system that can withstand the stresses. Of high importance is the modeling of transient overvoltages, which can be many times the DC link voltage and are a common cause of partial discharges that damage the insulation system of electrical machines. Since in hairpin windings the position of each conductor is known special precautions can be taken to prevent transient overvoltages. In this paper, a universally valid and automatable methodology is presented to model the voltage distribution in hairpin windings and identify transient overvoltages.

In this paper, a model for calculating the dynamic voltage distribution in electric traction motor windings under fast switching inverter feed is proposed. An Equivalent Circuit Model (ECM) approach is selected and outlined in detail. Required measurements on prototypes for model parameterization shall be avoided, as prototypes are only available in a late project stage. Hence, Finite Element (FE) models are proposed to calculate the required values of all network elements. The model results are compared with measurements for validation.

Nowadays, high performances and reliability are being required from the energy storage system in different fields of application, including hybrid and electric vehicles as well as grid-tied power converters for the integration of renewable energy sources. Therefore, with the increasing of lithium-ion batteries (LIBs) application, the estimation of the State of Charge (SoC) at both cell and pack levels represents a fundamental task to be performed by the Battery Management System (BMS) in order to optimally manage the operating conditions, maximize the overall performances while extending the useful life. However, the nonlinear characteristics of the LIB parameters and the measurement noise due to the accuracy of current and voltage sensors in real applications strongly affect the performances of traditional SoC estimation methods, such as Coulomb counting and Open Circuit Voltage observation, leading to significant errors. To overcome these issues, different model-based methods have been proposed in literature. In this paper, Kalman filter methods are investigated with aim of evaluating the variability of their performances with respect to the initial calibration of the covariance matrices and the specific operating condition. In addition, the benefits of a proposed adaptive algorithm combined with a state estimator are highlighted.

New technologies and materials for power electronic switching devices are gaining momentum. Indeed, wide-bandgap semiconductors, such as silicon carbide (SiC) or gallium nitride (GaN), manifest advanced and innovative properties regarding their switching performance. Thus, increasing the switching dv/dt rate and reducing switching power losses. However, faster switching transient enhances the insulating material stresses. Therefore, we developed a pulse generator based on a series connection of four SiC MOSFETs to produce super-fast transient pulses. After the electronic circuit design and implementation, we performed several tests showing the capability of the pulse generator and proving the correct operation under strict output load conditions. The best-achieved dv/dt rate with a 4.2 kV pulse amplitude is 155 kV/μs in no-load condition and 110 kV/μs on a 100 pF load capacitance.
