摘要

在无线电力传输(WPT)系统中，效率和电池充电速度是非常重要的因素。由于负载范围广，在恒定频率下实现高效率在这样的系统中是不可能的。此外，选择合适的充电场景对提高充电速度也有显著影响。本文提出了一种带半有源整流器(SAR)的串联-串联WPT系统，该系统同时采用变频和阻抗匹配机制，以达到最高的效率。为了提高电池充电初期的充电速度，采用恒功率-恒压(CP-CV)充电算法。

Design of High-Efficiency WPT Battery Charging System with Constant Power and Voltage

In wireless power transfer (WPT) systems, efficiency and battery charging speed are very important factors. Due to the wide range of loads, achieving high efficiency at a constant frequency is not possible in such systems. Also, choosing the right charging scenario can have a significant effect on improving the charging speed. In this paper, a series-series (SS) WPT system with a semi-active rectifier (SAR) is proposed, which uses the variable frequency and the impedance matching mechanism simultaneously to achieve the highest efficiency. Also, to increase the charging speed at the beginning of the battery charging, a constant power-constant voltage (CP-CV) charging algorithm is used.
