Conclusion and Outlook, and 47.9% (highly integrated) are reached together with a large value of 240 for the dynamic load current range. The converter is able to cover the full Li-ion input voltage range. The outlook proposes future research in areas such as integrated passives, electromagnetic emission properties of resonant converters, and multi-phase operation.作者: 刪減 時間: 2025-3-22 13:01 作者: 同音 時間: 2025-3-22 18:39 作者: 定點 時間: 2025-3-23 00:04 作者: Ardent 時間: 2025-3-23 04:44
