Power electronics technology plays an increasingly important role in modern energy utilization systems. Modern power electronics technology is becoming highly frequent, efficient, and reliable. However, there are still many challenges that need to be overcome [1,2,3,4,5,6]. This Special Issue focuses on the latest achievements of ensemble power electronics technologies, including the following aspects: novel topology of converters, modeling and control strategies, fault analysis and diagnosis methods, and new principle converters in wireless power transmission and other emerging applications. The purpose of this Special Issue is to provide opportunities for researchers in related fields to exhibit and exchange their latest achievements, establish a database of achievements in the field of power electronics, and provide solutions for related application fields.
A total of five papers related to various fields of power electronics technologies, as listed in Table 1, including power balancing strategy, multilevel voltage source converter, synthesis of non-bridge circuit, and dual two-level inverter configurations for open-end winding machines, are presented in this Special Issue. Wei et al. proposed a decoupled model predictive control power balancing strategy for a coupled inductor-based flying capacitor DC–DC converter to solve the power imbalance caused by the parameter differences in the coupled inductor. He et al. proposed a novel topology for a reinjection multilevel voltage source converter. This new topology retains all the functions of the RMVSC while offering flexible control of the reinjection circuit and ease of modularization, making it highly suitable for high-voltage and high-power applications. Nair et al. proposed a real time-decentralized droop controller and modified droop control considering the load dynamic for an islanded DC microgrid to enhance the voltage regulation at the DC bus and current sharing efficacy between the sources subject to load transients. Kampik et al. proposed an evaluation of the possibility of the synthesis of a non-bridge system for measuring the dielectric loss coefficient on the basis of a simple bridge circuit. Zerdani et al. presents a state-of-the-art review of the main dual two-level inverter configurations and their impact on the performance of the open-end winding machine.
Although submissions to this Special Issue have been closed, more in-depth research in the field of power electronics continues to address these challenges, such as power density, efficiency enhancement, high-voltage and huge power conversions based on next-generation wide-bandgap power switches, and the status and health diagnosis and prediction of power converters, among others.
