Abstract

The invention discloses a high-efficiency rectifier circuit covering a wide input power range. The rectifier circuit consists of a Wilkinson power divider, a first sub-rectifier circuit and a second sub-rectifier circuit. The Wilkinson power divider has a power ratio of one to two, and provides different input power for the first sub-rectifier circuit and the second sub-rectifier circuit. The first sub-rectifier circuit and the second sub-sub-rectifier obtain optimum rectification efficiencies at different input power. The first sub-rectifier circuit and the second sub-rectifier circuit are combined through the Wilkinson power divider, and the entire rectifier circuit has two power conversion efficiency peak values and is thus allowed to obtain a high rectification efficiency over a wider input power range. Moreover, at the same input power, the rectifier circuit has almost the same or higher efficiency as that of a single sub-rectifier circuit.

Description

technical field [0001] The invention relates to a high-efficiency rectification circuit, in particular to a high-efficiency rectification circuit covering a wide input power range that can be applied to the back end of a wireless energy transmission system. Background technique [0002] In recent years, battery-powered electronic devices, such as wireless sensors, have developed rapidly and achieved great success. However, the need for wired charging of traditional batteries makes them limited in application. The advent of infinite energy transfer systems has made these mobile electronic devices more efficient, reliable and easy to use. [0003] The rectifier is an important part of the infinite energy transmission system. It has features that improve the conversion efficiency of RF energy to DC energy. Among them, there are many types of rectifier implementation forms, such as the structure of using series diodes to form a rectifying circuit, using parallel diodes to for...
