A new harmonic-recycling (HR) rectifier is proposed. Different from conventional rectifiers using harmonic suppression, the proposed rectifier channels the fundamental component generated by the diode to another rectifying element optimized for low-power range, which enables more efficient RF–DC conversion. By implementing a HR unit, additional dc power can be collected with 18% and 11% enhancement in dc output voltage and RF–DC conversion efficiency, respectively. This provides an alternative and more effective method to extract dc power from the incident RF for wireless power transfer application.

用于高效远场无线电力传输的谐波回收整流器

提出了一种新的谐波回收 (HR) 整流器。与使用谐波抑制的传统整流器不同，所提出的整流器将二极管产生的基波分量引导到另一个针对低功率范围优化的整流元件，从而实现更高效的 RF-DC 转换。通过实施 HR 单元，可以收集额外的直流功率，直流输出电压和 RF-DC 转换效率分别提高 18% 和 11%。这提供了一种替代且更有效的方法，可以从入射 RF 中提取直流功率，用于无线功率传输应用。
