Special Issue Information

Dear Colleagues,

Power electronics has emerged as an enabling technology in the deployment of the next generation of systems, including transportation systems, motor drives, robotics, biomedical applications, renewable energies, smart grids, and data centers, among many others. The demand for higher efficiency, enhanced reliability, higher power density, specific power, and better thermal management poses stringent challenges for these power electronic converters to accommodate. The advent of wide bandgap (WBG) power semiconductors resulted in a paradigm shift of power electronics design through enabling high-temperature, high-density power conversion with improved efficiency. However, employing fast switching devices leads to higher dv/dt and di/dt at the switch nodes and drain/source paths, respectively, which poses great challenges in ensuring safe operation of the switching circuits, especially at an elevated temperature during steady state operation. This results in noise modeling and high-density optimized EMI filter design being areas of immense interest for WBG power electronics. Furthermore, any power electronic system design deals with two spaces: (i) design space, i.e., passive component parameters, (ii) performance space, i.e., efficiency, power density, cost, reliability, etc. It is very well observed from research that performance indices often follow trade-offs among each other for different combinations of design variables. In order to meet superior performance requirements from the designers’ end, the system design boils down to a multi-objective optimization problem for a given set of electro-thermo-mechanical constraints, which can potentially be tackled using genetic algorithm- and machine learning-based optimization methods. The optimization methods can be applied in (a) converter control with fast transient response along with stiff regulation, (b) design of magnetic components (inductors/transformers) as well as magnetic coil for wireless power transfer, (c) volume minimization of passive components along with reliability maximization.

The main aim of this Special Issue is to seek high-quality submissions that highlight emerging applications of high-density power converters, address recent fundamental breakthroughs in topological development as well as control of power electronics, multi-objective constrained design optimization of power converters, and reliable and cyber-resilient power electronics technologies. The topics of interest include, but are not limited to:

  • Multi-objective design optimization (based on machine learning/statistical learning/artificial intelligence) of power converter systems
  • EMI noise modeling and high-density filter design methodologies
  • Non-linear/optimal control schemes for transient performance improvement of power converters
  • WBG device characterization for high-frequency power electronics
  • High-temperature (>200oC) power electronics
  • Power electronics for transportation electrification and data centers

An 11-level switched-capacitor multilevel inverter (SCMLI) with 2.5 times boosting feature is presented in this paper. It can produce an 11-level output voltage waveform by utilizing 14 switches, 3 capacitors, 2 diodes, and 1 DC source. Only nine driver circuits are needed as the topology has three pairs of complementary switches and two bidirectional switches. It has inherent capacitor self-balancing property as the capacitors are connected across the DC voltage source during several states within a fundamental cycle to charge the capacitors to the input voltage. A detailed comparison shows the effectiveness of the proposed topology in terms of the number of switches, number of capacitors, number of sources, total standing voltage (TSV), efficiency, and boosting ability with the state-of-art recently proposed circuits. Subsequently, the performance of the proposed SCMLI is validated experimentally utilizing the nearest level control (NLC), a fundamental frequency-based switching technique. Full article

This paper presents a volumetric comparison among three possible optimized three phase EMI filter structures, a three phase PFC converter used in cutting edge applications, such as avionics, space or shipboard power systems. The size minimization of each of the filter structures, described in the paper, was performed utilizing the volumetric optimization methodology proposed in the paper. This paper theoretically demonstrates the design steps for choosing the appropriate filter component values and number of filter stages to achieve the smallest volume of the DM filter stage for any given EMI filter structure. While the validation of the proposed design methodology was done through a MATLAB simulation, an experimental verification was also performed by designing and comparing the optimized EMI filter structures for a 2.3 kW proof-of-concept of a three-phase boost PFC converter for more electric aircraft (MEA) applications to comply with the stringent EMI requirements of the DO-160F standard.

This paper presents a novel, scalable, and modular multiport power electronic topology for the integration of multiple resources. This converter is not only scalable in terms of the integration of multiple renewable energy resources (RES) and storage devices (SDs) but is also scalable in terms of output ports. Multiple dc outputs of a converter are designed to serve as input to the stacking modules (SMs) of the modular multilevel converter (MMC). The proposed multiport converter is bidirectional in nature and superior in terms of functionality in a way that a modular universal converter is responsible for the integration of multiple RES/SDs and regulates multiple dc output ports for SMs of MMC. All input ports can be easily integrated (and controlled), and output ports also can be controlled independently in response to any load variations. An isolated active half-bridge converter with multiple secondaries acts as a central hub for power processing with multiple renewable energy resources that are integrated at the primary side. To verify the proposed converter, a detailed design of the converter-based system is presented along with the proposed control algorithm for managing power on the individual component level. Additionally, different modes of power management (emulating the availability/variability of renewable energy sources (RES)) are exhibited and analyzed here. Finally, detailed simulation results are presented in detail for the validation of the proposed concepts and design process. Full article

The development of offshore wind farms (WF) is inevitable as they have exceptional resistance against climate change and produce clean energy without hazardous wastes. The offshore WF usually has a bigger generation capacity with less environmental impacts, and it is more reliable too due to stronger and consistent sea winds. The early offshore WF installations are located near the shore, whereas most modern installations are located far away from shore, generating higher power. This paradigm shift has forced the researchers and industry personnel to look deeper into transmission options, namely, high voltage AC transmission (HVAC) and high voltage DC transmission (HVDC). This evaluation can be both in terms of power carrying capability as well as cost comparisons. Additionally, different performance requirements such as power rating, onshore grid requirements, reactive power compensation, etc., must be considered for evaluation. This paper elaborately reviews and explains the offshore wind farm structure and performance requirements for bulk offshore power transfer. Based on the structure and performance requirements, both HVDC and HVAC transmission modes are compared and analyzed critically. Finally, a criterion for selection and increasing popularity of HVDC transmission is established. Full article
