Special Issue Information

Dear Colleagues,

The Special Issue titled “New Insights in Power Electronics: Prospects and Challenges” in the Electronics journal focuses on the intricate domain of power electronics and static power converters. This issue aims to provide a comprehensive exploration of the latest advancements, challenges, and future prospects within this critical field. Power electronics, with its fundamental role in energy conversion and management, stands as a cornerstone of modern electrical systems. Within this Special Issue, we aim to delve into various aspects of power electronics, ranging from theoretical advancements to practical implementations.

The articles featured in this issue will cover a wide array of topics, including novel converter topologies, advanced control strategies, modeling and simulation techniques, thermal management, reliability issues, and emerging applications of power electronic systems. Special attention will be given paid to the integration of renewable energy sources, such as solar and wind power, into the grid through static converters, thus addressing the challenges of grid stability, power quality, and grid-tie inverters.

Moreover, we will explore the latest developments in power semiconductor devices, such as wide-bandgap materials (e.g., SiC and GaN), which offer superior performance and efficiency when compared to traditional silicon-based devices. These advancements are driving significant improvements in power electronic systems, enabling higher power density, lower losses, and increased reliability. Additionally, the Special Issue will examine the role of power electronics in facilitating the electrification of transportation, energy storage systems, and smart grid infrastructure.

Through a combination of in-depth technical articles, case studies, systematic literature reviews, and expert insights, this Special Issue aims to advance the state of the art in power electronics and contribute to the development of sustainable and efficient energy systems. It serves as a platform for researchers, engineers, and practitioners to exchange knowledge, share best practices, and collaborate towards a greener and more sustainable future. Additionally, systematic literature reviews providing a comprehensive analysis and synthesis of existing research in this domain are also welcome.

Recently, the rapid proliferation of eco-friendly mobility solutions has driven an increasing demand for high-efficiency, high-power, compact, and reliable traction motors. In the eco-friendly mobility sector, electric mobility commonly employs Interior Permanent Magnet Synchronous Motors (IPMSMs) due to their high efficiency, high power, and compact size. However, ensuring reliability requires effective fault diagnosis. Among various faults, eccentricity in traction motors can degrade performance characteristics, including vibration, noise, and torque precision, thereby impairing driving performance. This paper proposes a novel winding method for Variable Reluctance (VR) resolvers and introduces a fault diagnosis approach for eccentricity using Finite Element Method (FEM) analysis. By employing this novel winding method, the direction of eccentricity occurrence can be effectively identified. Additionally, this method demonstrates robustness against defects, such as open-circuit faults, compared to a conventional winding method. Therefore, the proposed winding method contributes to improving the reliability and stability of IPMSMs through fault diagnosis and ensures robustness against open-circuit faults in the VR resolver.

This paper addresses cross-regulation in dual-output flyback converters. An original analytical framework is developed to model the impact of a balancing capacitor connected among a transformer’s secondary windings in order to mitigate the cross-regulation among different outputs. To validate the proposed model, a prototype dual-output flyback converter was built and tested for a wide range of load unbalances. The measured cross-regulation error was compared with the theoretical predictions provided by the proposed model, obtaining a tight fit, which confirms the validity of the proposed approach.

With the high integration of power electronic devices, wireless power transfer (WPT) systems are required to have output characteristics of different specifications that are independent of the load. However, existing methods for realizing dual-output WPT systems have problems such as complex circuits, cumbersome control schemes, low system stability, insufficient system space utilization, and unnecessary cross-coupling. Therefore, in order to solve the above problems, this paper proposes a dual-receiver WPT system with dual constant current (CC) output based on an integrated decoupling coil. In this system, the DD coil is wound vertically in series with the solenoid coil and serves as the first receiving coil to achieve energy transmission in the system. While the solenoid coil is used in the transmitting coil and the second receiving coil, and the coils are perpendicular to each other to achieve natural decoupling. Furthermore, the receiving coils are integrated together on the receiving side ferrite plate. Therefore, there is no cross-coupling interference in the system, which simplifies the system design. Firstly, the natural decoupling characteristics of the magnetic coupler and the coil optimization method are analyzed in detail theoretically. Secondly, a detailed mathematical analysis is performed on the dual CC output characteristics with different specifications that are load-independent and have zero phase angle operation. Again, the zero voltage switching of the inverter can be achieved by changing the compensation component parameters through simulation verification. Finally, a prototype with a rated power of 283 W is constructed for validation purposes. The first receiver delivers a CC output of 3 A, while the second receiver provides a CC output of 4 A, with the DC–DC conversion efficiency reaching a peak of 90.2%. The experimental results confirm the accuracy of the theoretical analysis. Full article
