Special Issue Information

Dear Colleagues,

Power electronics and wireless power transfer (WPT) technologies are rapidly converging to form the foundation of next-generation energy systems. The integration of high-frequency power conversion and contactless energy transfer is enabling new paradigms in electrification, including electric vehicles, autonomous systems, and distributed energy applications. In particular, recent advances in wide bandgap semiconductor devices, high-frequency inverter design, and resonant coupling techniques have significantly expanded the performance limits of integrated power conversion and WPT systems.

Despite these advancements, several technical challenges remain unresolved when power electronics and WPT are tightly coupled. These include switching-induced electromagnetic interference, harmonic generation, efficiency degradation at high frequencies, thermal management under high power density, and system-level optimization across power stages and coupling interfaces. Addressing these challenges requires a holistic design approach that bridges circuit design, electromagnetic field analysis, control strategies, and thermal engineering.

This Special Issue aims to collect high-quality contributions that explore the co-design, integration, and optimization of power electronics and WPT systems. We particularly welcome studies that demonstrate innovative concepts, experimental validations, and system-level solutions that go beyond conventional isolated approaches to power conversion or wireless transfer.

Topics of interest include, but are not limited to, the following:

  • Co-design and integration of power converters and WPT systems;
  • High-frequency inverter technologies for WPT applications;
  • Advanced modulation and control strategies for integrated systems;
  • Harmonic suppression and EMI mitigation in coupled systems;
  • Wide bandgap device applications (GaN, SiC) in WPT-integrated converters;
  • Magnetic design and coupling optimization considering converter operation;
  • Thermal management and reliability in high power-density integrated systems;
  • Modeling and system-level optimization of coupled power conversion and WPT;
  • Experimental prototypes and demonstrators of integrated systems;
  • Applications in electric vehicles, robotics, drones, and autonomous platforms.

We look forward to receiving your valuable contributions to this Special Issue.

This paper presents an adaptive combining power amplifier (PA) implemented in the ETGaN15 process. The proposed architecture eliminates the λ/4 impedance transformers required in conventional back-off efficiency enhancement techniques, employing instead a combining network composed solely of microstrip lines and capacitors. The proposed circuit dynamically performs load modulation and power combining according to the input power level, simplifying the overall impedance matching structure while improving efficiency in the output back-off region. The measurement results demonstrate a small-signal gain of 8 dB and a peak output power of 34 dBm across the 10 GHz band. The PA achieves a peak power-added efficiency (PAE) of 28% and a peak drain efficiency (DE) of 41%, while maintaining a PAE of 23% and a DE of 28% at a 6-dB output power back-off (OBO). Full article
