论文摘要
分布式激光充电（DLC）是一种用于移动电子产品的无线电源传输技术。与传统的无线充电系统类似，DLC系统只能提供恒定的电池电量。但是，锂离子电池需要动态输入电流和电压，因此需要电源，以优化电池充电性能。因此，DLC系统都不能优化电力传输效率和电池充电性能。我们首先提出了一个自适应DLC（ADLC）系统，以优化无线电源传输效率和电池充电性能。然后，我们分析ADLC的功率转换以描绘适应机制。最后，我们通过模拟评估了ADLC的功率转换性能，这说明了其通过节省至少60.4％的能源的效率提高，并与固定电源充电系统相比。
Distributed laser charging (DLC) is a wireless power transfer technology for mobile electronics. Similar to traditional wireless charging systems, the DLC system can only provide constant power to charge a battery. However, Li-ion battery needs dynamic input current and voltage, thus power, in order to optimize battery charging performance. Therefore, neither power transmission efficiency nor battery charging performance can be optimized by the DLC system. We at first propose an adaptive DLC (ADLC) system to optimize wireless power transfer efficiency and battery charging performance. Then, we analyze ADLC's power conversion to depict the adaptation mechanism. Finally, we evaluate the ADLC's power conversion performance by simulation, which illustrates its efficiency improvement by saving at least 60.4% of energy, comparing with the fixed-power charging system.
