Special Issue Information

Dear Colleagues,

The Guest Editor is inviting submissions to a Special Issue of Electronics on the subject area of the use of GaN and SiC technology to improve the performance of power semiconductor systems. Current trends within material engineering and development of perspective semiconductor devices have proven that wide bandgap technology represents the way to marry the contradictory requirements for power converters, i.e., high efficiency and simultaneously high-power density. There are numerous application areas where GaN power transistors can meet the strict requirements defined for the design of power semiconductor systems, i.e., from consumer applications up to industrial power converters. There is no limitation regarding where wide bandgap devices can be utilized, tested, and evaluated as the best in class choice of designers and electrical engineers. Thermal performance and reliability are also increasing demands for the application of power converters, while wide bandgap technology together with novel design approaches enable achieving satisfactory results. This Special Issue will focus on but is not strictly limited to:

  • GaN and SiC power device testing, simulation, and modelling;
  • High switching frequency power converter topologies;
  • Progressive topologies utilizing GaN and SiC power transistors;
  • Control techniques and control systems for high switching frequency power converter topologies;
  • Design issues related to advanced power semiconductor converters using SiC and GaN technology;
  • Optimized driving circuits for wide bandgap devices;
  • GaN and SiC power modules for low voltage and high voltage applications;
  • Thermal performance of power converters enhanced by wide bandgap devices;
  • Magnetic component design issues related to the use of wide bandgap devices.

This paper evaluates the performance of the high-voltage wide-band gap SiC power transistors equipped within 3-phase bridgeless 3 kW PFC circuit. The main aim of the study is the experimental evaluation of the dynamic properties and driving power requirements of the transistors, for which the parameters are similar. These are competing products from different manufacturers, while the selection criterion was the same type of package technology (7 pin D2PAK). Second, the effect of the transistor type was analysed in terms of the performance efficiency of the PFC circuit. Within the analysis, the driver circuit was constructed first, and adapted to high voltage transistor driving. During individual measurements, the driver remained the same, while gate-driver losses were analysed for individual transistors. The obtained results reveal differences related to requirements on driving power, as well as to the dynamics of transistors themselves. At the end of the paper, the evaluation of efficiency for different operating conditions of a constructed PFC converter is realized. The obtained results provide a more detailed overview of the dynamic properties of transistors and their impact on the resulting efficiency of the main circuit also in terms of driving requirements.

The aim of this work is to investigate the influence of circuit elements on the properties of the selected power factor correction (PFC) topology. Active or passive PFC serves to increase the power factor (PF) and reduce the total harmonic distortion (THD) of the mains current. As a result, the distribution network is lightened due to its interference caused by connected electronic devices. An important indicator of all electronic converters is efficiency. Therefore, the work deals with the analysis of possible efficiency improvements in conjunction with the use of technologically new active components. Detailed experimental analyses and optimization procedures are performed in terms of the influence of transistor structures (SiC and GaN) on the qualitative indicators of the proposed PFC converter for a wide operating spectrum. The synthesis of the obtained results is given, together with recommendations for optimal selection and optimal design of PFC main circuit elements with regard to achieving peak efficiency values.
