Special Issue Information

Dear Colleagues,

The history of power electronics is both extensive and rich. At the inception of the 20th century, it surfaced with the presentation of a rectifier that transforms high-voltage alternating current (AC) into direct current (DC). Currently, power electronics play a pivotal role in renewable energy systems, and for the transition from centralized to decentralized distribution systems, they are essential components. PV and wind are the main renewable energy resources. The PV Europe Solar Technology and Applications data show that global PV installation has increased up to 50% in 2023 and will reach 351 GW. Meanwhile, the worldwide installation of wind turbines is going to increase to 906 GW by the end of 2023. The handling of all these is performed by power electronics technology. Consequently, the demand for designing and modelling dependable and cost-effective power electronics devices and their control systems is high. 

The main aim of this Special Issue is to seek high-quality submissions that highlight and address recent breakthroughs in the modelling, design, application, and control of power electronics for smart grids, off-grid and grid-connected renewable energy systems, etc.

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

  • Power electronics applications in power systems;
  • Power converter design and applications;
  • Filter design and applications for power converters;
  • Control techniques for power converters;
  • Smart grids;
  • AC, DC, and hybrid microgrids;
  • High voltage direct current (HVDC);
  • Distributed generation, fuel cells, and renewable energy systems;
  • Electric drivers and applications;
  • Renewable energy, including wind, solar, and wave, etc.;
  • Power electronics for electrical vehicle charging stations.

To enhance the power density of LLC resonant converters, multilayer planar inductors are required. However, multilayer planar inductors have high parasitic capacitance, which may cause inductor current ringing in LLC resonant converters, leading to EMI problems. In this paper, it is found that by using interleaved winding inductors, compared with traditional winding inductors, the parasitic capacitance of multilayer planar inductors is reduced, which can reduce current ringing, without sacrificing power density and increasing manufacturing complexity. The method used to analyze current ringing is to establish an impedance model, and the parasitic capacitance of the interleaved winding inductors is verified by FEM simulations. The analysis is validated in an LLC resonant converter prototype. Full article

Ferroresonance, as an undesirable disturbance, leads to significant overvoltage and distorted waveforms. This phenomenon can be highly damaging to voltage transformers and other parallel-connected equipment and can entail catastrophic consequences. This paper aims to design and study a solid-state ferroresonance-suppressing circuit (SSFSC) to protect voltage transformers (VTs) together with other parallel-connected equipment in wind generation systems from the adverse effects of the ferroresonance phenomenon. The proposed structure consists of low-voltage circuits, including power IGBTs. The excellent performance of the proposed SSFSC in suppressing ferroresonance overvoltage in wind generation VTs has been authenticated by analyses conducted utilizing a wind generation system model. In order to validate the performance of the proposed SSFSC, detailed analytical studies and time-domain simulations have been carried out employing a MATLAB/Simulink environment. The results verify that the proposed SSFSC can effectively suppress ferroresonance phenomena in VTs and mitigate their accompanying overvoltages with a high operational speed. Full article
