In modern DC distribution networks both consumer and prosumer devices are interfaced to the grid via power converters equipped with suitable filtering circuitry to mitigate conducted electromagnetic interference (EMI), also referred to as conducted emissions (CE). However, the presence of asymmetries in the converter, such as the deviation of the component parameters from the designed ones and possible device failure, can significantly alter the input current and voltage waveforms while the device still works satisfactorily. This inevitably leads to an increase in the harmonic pollution in the power grid, being the EMI filters designed for acting on different waveforms. This paper investigates the effect that non-idealities of power switches have on the input current of an H-bridge inverter.

The growing popularity of Electric Vehicles (EVs) makes a growing need to build energy-efficient battery chargers to charge EVs batteries faster than before. Newly designed EVs have larger battery capacities and higher voltage ranges than their previous versions. Therefore, the recent onboard battery pack voltages are increased to 700-800 V ranges, to increase the battery capacities and reduce the charging time. On-Board Chargers (OBCs) are an essential part of plug-in battery EVs and hybrid vehicles. The most recent stage in the technological development of the available battery chargers is the two-stage approach. In this paper, the available two-stage ac-dc approach and single-stage matrix converter are compared comprehensively in terms of size, efficiency, and applicability to see which approach is more efficient. Finally, both of the structures are simulated in PSIM software with 12 kW output power, 800 V battery voltage, 100 kHz high switching frequency, and three-phase 50 Hz and 230 V grid to validate the theoretical analysis.

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.

The paper presents a method for derivation of the minimum split DC link capacitance in three-phase three-level DC-AC converters operating with unity power factor with neither active balancing circuits nor AC zero sequence injection. It is shown that due to the fact that partial DC link voltages and AC-side phase voltages obtain extremum values at different instants, it is possible to reduce the minimum value of the former below maximum value of the latter while still ensuring correct operation of the power stage. Minimum attainable split DC link capacitance values are therefore obtained according to boundary case of tangency between the above-mentioned voltages. Analytical derivations are accurately verified by simulations and experiments, demonstrating close agreement.

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.
