Special Issue Information

Dear Colleagues,

Power electronics is present in our daily life, from low-power applications, such as smartphones and electric vehicles, to high-power applications, such as high-voltage direct current. Power Electronics is also used in: generation systems, such as wind and solar renewable energy sources; distribution systems, such as solid state transformer; and transmission systems, such as flexible AC transmission systems. Therefore, it is no surprise that up to 70% of electrical energy is now processed by Power Electronics, and this number will increase in the future. Thus, many researchers are currently working to increase Power Electronics’ efficiency, reliability and applicability to meet new electrical grid codes, with optimal steady-state and transient systems operation being important players in the transition to a carbon-free energy system. This Special Issue aims to present and disseminate the most recent advances related to Power Electronics systems, such as new semiconductor technologies, converter design and topologies, real-time digital modelling and simulation, advanced control, and novel applications. Topics of interest for publication include, but are not limited to:

  • Wide bandgap semiconductors;
  • Novel converter designs/topologies;
  • Real-time digital simulation;
  • Power Electronics in industrial processes;
  • Power Electronics in transportation;
  • Advanced controls applied to Power Electronics;
  • Renewable energy sources based on Power Electronics;
  • Power Electronics applied in generation, distributions and transmission systems;
  • Novel Applications with Power Electronics.

This article presents a novel four-port DC–DC converter designed to integrate photovoltaics, fuel cells, and supercapacitors with one DC charging single-output port with a reduced component count. The proposed converter ensures an efficient power management strategy to manage the load power demand and optimize the power flow from the sources. The power management controller helps enhance the performance of the system by dynamically prioritizing the sources based on their availability and the demand of the load. A comprehensive reliability analysis is conducted to measure the converter’s robustness under varying load conditions, proving its suitability for real-world applications. The proposed topology’s performance was validated in three different scenarios for 1 kW using a simulation tool, and experiments in the laboratory were conducted. The failure rate and efficiency of the system are analyzed, and the converter promises a 96.5% efficiency for 1 kW and a failure rate of 4.6216 × 106 failures per hour. The simulation and experimental results validate the converter’s performance, highlighting its superior efficiency, reliability, and scalability. Full article
