Special Issue Information

Dear Colleagues,

The penetration of wide-bandgap (WBG) devices, such as silicon carbide and gallium nitride, is increasing in the industry due to their superiorities of reduced switching loss, lower reverse recovery current, and higher operation temperature. It enables power converters to operate under higher switching frequencies which can significantly increase the power density.

The application of WBG devices also poses challenges for the power converter design. The increases in electromagnetic interference (EMI) noise raise stability concerns, while the high switching frequency requires improved control strategies. Both the industry and academia have dedicated much effort into developing novel solutions for the application of WBG devices.

This research topic aims to collate state-of-the-art efforts in developing power converters with WBG devices. All efforts including high-quality original research and review articles in this field that help to improve the power density of converters are welcome in this research topic. Potential topics of interest include, but are not limited to, the following:

  • The modeling of WBG devices;
  • The application of artificial intelligence in the power converter modeling and control;
  • The packaging of the wide-bandgap semiconductor devices;
  • Advanced gate driving technologies for WBG devices;
  • Novel high-switching-frequency converter topologies;
  • Control strategies of high-frequency power converter;
  • The application of WBG devices in distributed generation and transportation electrification;
  • Reliability issue of the power conversion system with WBG devices.

Wide bandgap (WBG) power semiconductors can achieve high efficiency and power density due to their low on-resistance and fast switching speeds. However, the fast-switching speed induces voltage to the parasitic inductance in the circuit, causing a significant overshoot in the drain-source voltage of the devices and the ringing of the drain current due to resonance with the parasitic capacitance. Thus, minimizing parasitic inductance is necessary for driving WBG power semiconductors in a stable manner. This paper proposes a three-dimensional lattice structure that reduces parasitic inductance through horizontal and vertical magnetic flux cancellations within a printed circuit board (PCB). The relationship between the magnetic flux cancellation and the parasitic inductance is analyzed, and the magnetic flux cancellation in the proposed structure is described. In addition, a practical PCB layout design procedure based on the proposed structure is provided. Simulation results demonstrate a 55.8% reduction in parasitic inductance, and experimental results show reduced overshoot and ringing at the switching transient, resulting in a 26% reduction in switching loss. As a result, the proposed method can improve the efficiency and stability of WBG device-based power converters. Full article
