The main purpose of this paper is to provide a methodology for a condition assessment of an electrical machine as a significant asset that requires maintenance. The remaining useful life (RUL) and the failure probability of an alternator with salient poles rotor are determined for various temperature profiles in order to demonstrate how RUL and failure probability change under different levels of main stress factor which is a temperature in this case. As a nominal lifetime changes non-linearly in the relation to the stress factor, the consumed RUL and reliability change as well. The most stressed location was identified and the empirical power-law aging model for a particular thermal class of electrical insulation system (EIS) was selected for the RUL estimation. Subsequently, the exponential and Weibull distribution incorporating parameters obtained through literature research were used to evaluate the failure probability. The numerical and graphical results were obtained via the custom script which analyzed a huge bulk of data recorded during one year of continuous device’s operation.

This paper investigates the computation of three-level optimized pulse patterns (OPPs) with zero common-mode voltage (CMV). To do so, a set of linear constraints that guarantee zero CMV is derived, and a systematic way of implementing it is presented. Moreover, to alleviate the increased computational demands of the associated optimization problem, a method that can reduce the computational time of three-level OPPs with zero CMV by up to 99% is proposed. Finally, to mitigate the increased current harmonics due to the CMV elimination, the symmetry requirements of the OPPs are relaxed. In doing so, as shown by the presented numerical results, the current quality can be improved, but alas, only marginally and over a limited range of modulation indices.

When modeling a thermoelectric harvester operating at low (below 100 degrees Celsius) and ultra-low (below 10 degrees Celsius) temperature gradients, the output power of the harvester is small, which means that even minor errors in the model parameters can lead to an error exceeding the result itself. The proposed dimensional analysis allows us to narrow down the number of model parameters, leaving only those parameters that can be measured with sufficient accuracy. In addition, a guide for the optimal selection of a thermoelectric module for a given thermal path is proposed. Experimental data confirm the theoretical analysis.

The reduction of CO2 emissions in the transport sector is one of the main objectives of the railway industry. Reliable railway operations require a dynamic and reliable energy supply and a direct access to renewable energy sources. Stationary fuel cell systems allow a decentralised power supply to reduce the grid dependency and allow the direct usage of green hydrogen, which can be produced in the vicinity of the railway line. The good transportability of hydrogen as a long-term energy storage medium in combination with the low maintenance and infrastructure cost of stationary fuel cells make hydrogen a viable solution for the electrification of some railway lines. Because of the good efficiency and the possibility of usage in co-generation systems, solid-oxide fuel cells systems would support the targeted environmental goals. By utilising and extending the existing infrastructure of catenary electrified tracks and operating with a simplified mobile application, a low maintenance and efficient stationary energy generation technology is proposed in this paper, to allow a cost-and energy-efficient decarbonisation of the railway industry.

The growing popularity of electric vehicles has led to more demanding requirements for on-board chargers (OBCs) in terms of size and efficiency as well as functionalities, e.g. world-wide compatibility and bi-directionality. The state-of-the-art solution of OBCs is a phase-modular design which comprises a large number of components and is thus inherently limited in the achievable power density. The next generation of OBCs are therefore true three-phase topologies like the B6/B8 topology featuring 1200V-rated SiC MOSFETs which can be merged into a unified topology for single- and three-phase compatibility. Further power density improvements demand a transition towards multi-level topologies with 600V-rated GaN HEMTs which allow to break the performance barriers of classic 2-level topologies. This is derived for the PFC and the DC/DC stages based on fundamental scaling laws as well as Pareto optimizations of the employed passive components. As an outlook for further power density increases, on the one hand the concept of the non-isolated OBC, and, on the other hand, the single-stage power conversion enabled by monolithic bi-directional GaN HEMTs are described.

Boost converters (BCs) are main parts of Photovoltaic (PV) systems with their major role in boosting and regulating the output voltage of PV panels to facilitate a stable load/grid connection in isolated/grid-connected mode of operation. Nevertheless, the inherent variable characteristics of PV system and loads make the control of such systems challenging. In this regard, the current study proposes a new control method based on converted hysteresis sliding mode control technique (CHSMC) to address and solve this challenge. In this approach, we first develop the control law according to the hysteresis modulation concept and then extent it to the pulse width-modulation (PWM)-based SMC. This makes the design steps more straightforward and limits the control efforts and provides a fixed switching frequency SMC technique. The main feature of this approach is its robustness against simultaneous variations in both the input voltage and the load current. The simulation results using MATLAB demonstrate the qualification of the proposed approach in regulating the load voltage over the conventional perturbation ampersand observation (PO) algorithm for controlling of PV packages.

There is increasing penetration of dc native renewable technologies, such as batteries and photovoltaics in the distribution grid. These renewable technologies can be interconnected with dc microgrids, which in turn often have a bidirectional connection with the ac distribution grid to enable energy exchange. For safety reasons, this connection is often galvanically isolated with a transformer. This paper presents a single stage high frequency link converter, based on an indirect matrix converter. A three leg four wire configuration is proposed to be able to operate in unbalanced conditions and provide various ancillary grid services. A digital controller is developed to control the grid currents and eliminate distortion at the zero crossing of the matrix converter. The results are verified with a PSIM model.

The increased number of distributed generation sources in distribution networks in recent years has emphasized the importance of their accurate and computationally efficient modelling. The development of efficient models becomes more difficult and complex with the introduction of novel controllers that aim to support the grid, often emulating the operation of passive circuit elements. One of such controllers has been recently proposed that emulates the operation of an admittance to support the voltage at the point of the converter grid connection. In this paper, an aggregate model of distributed energy resources controlled using virtual admittance approach and connected in parallel is derived. The resemblance of the controller to classical circuit elements is used to obtain an equivalent circuit for each converter including its controller part and the distribution line connecting it to the main grid. Then, circuit analysis techniques are applied to synthesize the aggregate model of all the parallel converters in the network, simplifying the assessment of their combined effect on the rest of the network and reducing the computational burden. Simulation results from Matlab and its SimPowerSystems toolbox are used to validate the accuracy of the proposed model.

The integration of renewable sources to catenary-powered electric traction systems is a paramount step to satisfy sustainability and smart city objectives, albeit necessitating accurate simulations of the infrastructure. This paper presents an innovative trolleybus network simulator, characterised by the modularity of the catenary model and built on an intuitive graphical user interface that offers significant topological change flexibility. The model is distinguished by high precision and moderate processing effort, bridging the gaps of existing block-based simulation tools. A graphical analysis of the voltage distribution evaluated in a section of Bologna’s trolleybus network shows the advances in precision of the proposed model.

The fast-switching behavior of Silicon Carbide (SiC) Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) has made these devices an ideal technology for high-frequency converters. However, parasitic circuit layout and other stray inductances in combination with the high di/dt and the device output capacitance cause excessive voltage overshoot across the MOSFETs. This paper presents a three-level voltage source gate driver suitable for minimizing the voltage overshoot in SiC MOSFETs operating in synchronous rectification mode. The operating principle of the driver relies on the trajectory of the gate-source voltage of the SiC MOSFET, which is adjusted in order to operate the device in active region. The driver’s performance has been experimentally validated on a synchronous DC/DC flyback converter rated at 70V and 500W. From the experiments, it is observed that using the proposed gate driver, the overvoltage across the SiC MOSFETs is minimized by approximately 13% compared to a conventional two-level gate driver.
