摘要/Abstract

摘要：

为了提高微波无线电能传输系统中整流电路的转换效率,文中提出了一种基于新颖谐波控制结构的紧凑型高效整流电路。所提整流电路简化和改进了常规滤波器,将基波和三次谐波反射回整流电路,并且阻断二次谐波进入负载,实现滤波功能。同时能够减小肖特基二极管两端电压和电流波形的交叠,进一步降低损耗。引入感性二极管补偿支节来补偿二极管在基频处的容性阻抗,对三次谐波呈现开路特性以实现能量回收。对所提整流电路进行了仿真实验,结果证明该电路具有优越性。

Abstract:

In order to improve the conversion efficiency of the rectifier circuit in microwave wireless power transmission system, a compact high-efficiency rectifier circuit based on the novel harmonic control structure is proposed in this study. The conventional filter is simplified and improved in the proposed rectifier circuit, which can reflect the fundamental and third harmonics back to the rectifier circuit,and prevent the second harmonic from entering the load to realize the filtering function. At the same time, it can reduce the overlap of voltage and current waveforms across the Schottky diode to reduce the losses further. On the other hand, the inductive diode compensation branch is introduced to compensate the diode capacitive impedance at fundamental frequency and turns to an open circuit to block the third harmonic for power recycling. The proposed rectifier circuit is simulated and the results show that the circuit is superior.

Key words: microwave wireless power transmission, microwave rectification, harmonic control structure, inductive impedance, overlap loss, power recycling, Schottky diode, capacitive impedance
