Electromagnetic energy collecting and storage and power supply device based on broadband wave absorber

Abstract

The invention discloses an electromagnetic energy collecting and storage and power supply device based on a broadband wave absorber. The electromagnetic energy collecting and storage and power supply device comprises an electromagnetic energy receiving and feed network module, a circuit impedance matching and filtering module, a rectifying module, a self-power DC-DC (direct current-direct current) boosting module and an energy storage module, wherein the output end of the electromagnetic energy receiving and feed network module is connected with the input end of the circuit impedance matching and filtering module; the output end of the circuit impedance matching and filtering module is connected with the input end of the rectifying module; the output end of the rectifying module is connected with the self-power DC-DC boosting module; the output end of the boosting module is connected with the power source input end of the energy storage module; the electromagnetic energy receiving and feed network module comprises the broadband wave absorber. The electromagnetic energy collecting and storage and power supply device has the advantages that the electric energy which is converted from the space electromagnetic wave and is received by a broadband electromagnetic energy receiver with high absorbing efficiency is rectified and filtered to be changed from alternating current into direct current, and then the electric energy is stored into the energy storage device (supercapacitor); a passive energy storage device which can work for a long time is provided.
