Special Issue Information

Dear Colleagues,

The ever-expanding computational and memory capacity of computers has meant that electromagnetic and circuit simulation are being increasingly deployed. The use of simulation offers the possibility to accelerate the time-to-market of new converters, discrete devices, or entire assemblies for energy conversion by drastically reducing prototyping time. Simulation models can reach high degrees of detail and it is now increasingly common to couple several related physical phenomena through the so-called multi-physics simulation.

Next to simulations based purely on software, they are developing more ways for systems to use hardware-in-the-loop (HIL), in which the dynamic physical system to control is emulated through hardware architectures in a position to reproduce the physical behavior of the real system, or its parts, through the interpretation of a real-time mathematical representation of the same system. It is for these reasons that the platforms for HIL simulation are becoming an essential tool for the testing of embedded systems.

Modeling and simulation are therefore becoming fundamental tools, as much for industrial design as for academic research, in understanding and predicting the operations and performances of converters and electric drives and their control techniques, conversion devices, as well as magnetic components, such as inductors and transformers. However, simulation and modeling have many challenging aspects that have engaged the research efforts of the scientific community; for instance, methodologies for building reliable models, the integration of different modalities of modeling and simulation, the development of efficient formulations from the point of view of time computing, and the development of adequately matching and converging models for the recent technologies of wide-bandgap power devices.

This Special Issue aims to address all subjects of scientific interest in the field of power electronics and electric drives that look both to specific applications on individual components and systems in their completeness and complexity.

Potential topics include, but are not limited to, the following:

  • Numerical methods for circuit and electromagnetic field simulation;
  • Loss characterization and prediction of passive components;
  • Modeling, simulation for EMI analysis and reduction methods in power electronics
  • Multi-physics system modeling of power converters
  • Electrical and thermal modeling of power switches
  • Simulation for design and optimization
  • Methodologies, and instruments for model verification
  • Multi-modal and Multiphysics simulation
  • Real-time and HIL simulation
  • Digital twining

This paper analyses the multi-objective design of an inductor for a DC-DC buck converter. The core volume and total losses are the two competing objectives, which should be minimised while satisfying the design constraints on the required differential inductance profile and the maximum overheating. The multi-objective optimisation problem is solved by means of a population-based metaheuristic algorithm based on Artificial Immune Systems (AIS). Despite its effectiveness in finding the Pareto front, the algorithm requires the evaluation of many candidate solutions before converging. In the case of the inductor design problem, the evaluation of a configuration is time-consuming. In fact, a non-linear iterative technique (fixed point) is needed to obtain the differential inductance profile of the configuration, as it may operate in conditions of partial saturation. However, many configurations evaluated during an optimisation do not comply with the design constraint, resulting in expensive and unnecessary calculations. Therefore, this paper proposes the adoption of a data-driven surrogate model in a pre-selection phase of the optimisation. The adopted model should classify newly generated configurations as compliant or not with the design constraint. Configurations classified as unfeasible are disregarded, thus avoiding the computational burden of their complete evaluation. Interesting results have been obtained, both in terms of avoided configuration evaluations and the quality of the Pareto front found by the optimisation procedure. Full article

Power electronics, as an enabling technology in most renewable energy systems, is gaining attention as the penetration of renewable energy sources increases. Wide-bandgap power electronics are of particular interest due to their superior voltage blocking capabilities and fast switching speeds. They can viably be considered in the renewable energy sources, especially as the penetration of wind energy is expected to increase by a great extent in the upcoming years. In this paper, a comparison of Silicon Carbide-based and Silicon-based wind energy conversion systems has been performed, as it is crucial in understanding the benefits of adopting wide-bandgap-based solutions at a commercial level. For this analysis, a 2 MW permanent magnet synchronous generator-based wind conversion system with a bidirectional full-scale frequency converter comprised of two back-to-back inverters is considered. The efficiency, cost, and total volume of the passive components comparison have been conducted for Silicon- and Silicon Carbide-based converters. The comparison presented is a fair comparison, meaning that the converters are designed with modules of the same power ratings. Wind energy systems are compared both for the same switching frequency (low switching frequency suitable for IGBT modules) and also considering a Silicon Carbide-MOSFET-based converter working at high switching frequencies. The comparison is performed in PLECS simulation tool, using the PLECS libraries for different modules obtained from the manufacturers’ experimental data. The results show the benefits of using the Silicon Carbide-based converter when it comes to volume reduction in the passive components and provide insights to what is missing in order to achieve overall system volume and cost savings.

Increasing the power density in switched mode power supplies is one of the main goals in power electronics. This aim can be achieved by using smaller inductors operating at partial magnetic saturation. In this work, a partially saturating ferrite core inductor is exploited in a switching DC-DC boost converter, regulated through nonlinear model predictive control. A nonlinear behavioral inductor model, identified through experimental measurements, accounts for both magnetic saturation and losses. The simulation results show that the converter output voltage is correctly regulated and the imposed current constraints are fulfilled, even when partial magnetic saturation occurs. Comparisons with traditional control techniques are also presented. Full article
