| contents | This letter proposes a targeted-subharmonic-eliminating pulse density modulation (TSE-PDM) method for SS- compensated WPT systems. By designing a noise transfer function with notch characteristics, the subharmonic components which excite current abnormal oscillations were eliminated. Simulation and experimental results demonstrate the effectiveness of the TSE-PDM in suppressing current abnormal oscillations. The proposed method is easy to implement in either primary or secondary side of the WPT system and exhibits a certain tolerance to deviations in NTF design, representing the most straightforward method for abnormal oscillation suppression in PDM controlled WPT systems. |
