用于无线电能传输的分段矢量脉冲频率调制三电平变换器

Multilevel converters have attracted more and more attention for their advantages over the two-level converters in breaking voltage limitation and multichannel wireless power transfer (WPT), but their switching loss is unbearable due to the lack of an effective soft-switching modulation method. To fill this gap, this article proposes and implements a segmented-vector pulse frequency modulation (SV...
