Randomized trial evaluates a new Buck converter's effectiveness in improving voltage regulation during WPT applications, indicating significant performance enhancement.
Key Points
This study aims to enhance the performance of wireless power transfer systems by addressing limitations associated with conventional Buck converters.
Proposed a Buck converter topology with an active switch in series with the input capacitor.
Systematically analyzed operating modes, steady-state behavior, and small-signal characteristics.
Developed a tailored control strategy for independent regulation of capacitor charging times.
Settling time was reduced by approximately 83%, improving responsiveness.
Negative undershoot was substantially suppressed, maintaining stable voltage.
The converter demonstrated high efficiency and enhanced dynamic performance compared to conventional topologies.
