一种基于新颖谐波控制结构的紧凑型微波整流电路
A Compact Microwave Rectifier Circuit with Novel Harmonic Control Structure
摘要
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 pro-posed in this study.The conventional filter is simplified and improved in the proposed rectifier circuit,which can re-flect 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.关键词
