Dual-Module Ultrawide Dynamic-Range High-Power Rectifier for WPT Systems

Blog Article

Rectifier plays a pivotal role in wireless power transfer systems.While numerous studies have concentrated on enhancing efficiency and bandwidth at specific high-power levels, practical scenarios often involve unpredictable power inputs.Consequently, a distinct need arises for a rectifier that demonstrates superior efficiency French Door Closing Bar across a broad range of input power levels.

This paper introduces a high-power RF-to-DC rectifier designed for WPT applications, featuring an ultrawide dynamic range of input power.The rectification process leverages a GaN (gallium nitride) high electron mobility transistor (HEMT) to efficiently handle high power levels up to BLUSH TOASTED CINNAMON #1215 12.6 W.

The matching circuit was designed to ensure that the rectifier will operate in class-F mode.A Schottky diode is incorporated into the design for relatively lower-power rectification.Seamless switching between the rectification modes of the two circuits is accomplished through the integration of a circulator.

The proposed rectifier exhibits a 27.5 dB dynamic range, achieving an efficiency exceeding 55% at 2.4 GHz.

Substantial improvement in power handling and dynamic range over traditional rectifiers is demonstrated.
