摘要

提出了一种用于无线电力传输的高效有源整流器。采用了基于反向电流检测和偏置电流控制的自适应断延时补偿。在商用0.18\mu\ mathm {m}$ CMOS技术上的仿真结果表明，该方案有效地消除了比较器关闭延迟的影响，当整流器工作在13.56MHz时，其峰值效率为92.5%。

A High-Efficiency Active Rectifier with Adaptive Off-Delay Compensation for Wireless Power Transfer Systems

A high-efficiency active rectifier for wireless power transfer is presented in this work. Adaptive off-delay compensation is adopted that is based on reverse current detection and bias current control. Simulation results in a commercial 0.18\mu\mathrm{m}$ CMOS technology show that the proposed scheme effectively eliminates the influence of the off-delay of the comparator and the peak efficiency of the rectifier is 92.5% when the rectifier works under 13.56MHz.
