该论文提出了一种42W可重构双向功率传输电压调节电缆，旨在解决USB Type-C Power Delivery快速充电中紧凑便携设备的热量管理问题。通过在电缆中集成电压调节和双向功率传输功能，将热量从设备内部转移到外部，从而在保持设备小型化的同时实现高效散热。
Instituto Superior Tecnico/University of Lisboa, Lisbon, Portugal 1 2 The universal serial bus (USB) has become really universal in recent years, with power delivery and all kinds of data protocols connected through a single Type-C port. In particular, the USB Type-C Power Delivery (PD) standards allow the cable to deliver 100W of power or more. However, the thermal issue becomes the limiting factor for fast charging an extremely compact portable device. How to move the heat out of the device, meanwhile keeping the device small and thin, becomes a question of great concern. An integrated charger involves a switching power converter, in which the power inductor is one of the main sources of power loss, besides occupying the largest area. To address this problem, an attractive solution is to relocate the power inductor in a DC-DC converter from the high-current output side to the low-current input side [1–3]. Such inductorfirst topologies considerably reduce the average current on the in
