Abstract

The invention discloses a high-efficiency dual-frequency rectifying circuit. The high-efficiency dual-frequency rectifying circuit comprises an upper layer microstrip structure, an intermediate dielectric substrate and a bottom layer metal floor, wherein the upper layer microstrip structure is printed on the upper surface of the intermediate dielectric substrate; the bottom layer metal floor is printed on the lower surface of the intermediate dielectric substrate; and the upper layer microstrip structure comprises a dual-frequency impedance matching network, a voltage doubling rectifying circuit structure, a harmonic suppression network and a load end which are connected in sequence. According to the high-efficiency dual-frequency rectifying circuit, due to the harmonic suppression network, the rectifying efficiency can be improved; due to the voltage doubling rectifying structure, the output voltage can be increased; and finally, by virtue of the regulation and control on the input impedance, the dual-frequency impedance matching network is designed, so that high rectifying efficiency of the disclosed rectifying circuit at two frequencies can be realized.

Description

technical field [0001] The invention relates to a microwave rectification circuit, in particular to a high-efficiency dual-frequency rectification circuit. Background technique [0002] Most of the contemporary energy transmission is transmitted in the form of cables. These transmission methods not only consume a lot of manpower and material resources, but also in the environment of insufficient space, harsh environment and complex terrain, the use of cables will be greatly restricted. Microwave Power Transmission is an energy transmission method that converts energy into microwaves and emits them from the transmitting end, and propagates them to the receiving end in free space. It breaks the traditional way of transmitting electric energy through cables and opens up A new way of energy transmission. [0003] Microwave energy transmission technology converts direct current into microwave energy through a microwave generator, and transmits it efficiently after being focused ...
