【摘要】 本文提出了一种应用于射频/微波能量收集系统的自适应可重构整流电路,该整流电路由高/低信号功率通路、开关等组成。整流电路通过检测输出电压自动选择相应信号通道工作,从而实现输入信号范围拓展。仿真结果表明,工作在2.45GHz的自适应可重构整流电路能够在-5～20 dBmW范围内其最大功率转换效率的80%,相对于单一整流电路,其输入信号范围拓展了近一倍,同时其具有自适应可重构特点。更多还原

【Abstract】 An adaptive reconfigurable rectifier for RF/microwave energy harvester is proposed in this paper.The rectifier is composed of high powe/low power signal pathes,switches and so on.Rectifier detects the output voltage and chooses the relative path for operation to extend the range of input power..Simulation results show that the adaptive reconfigurable rectifier can operate at 2.45 GHz from-5 dBmw to 20 dBmw with 80% maximum power conversion efficiency.Compared with convertional rectifier its operating input power range extend close twice with the merit of adaptive reconfiuration.更多还原
