MPT中基于LabWindows/CVI的微波波束自适应调节
Adaptive adjustment on microwave beam based on LabWindows/CVI in a microwave power transmission system
摘要
Abstract
In order to realize the highest transmission efficiency in a Microwave Power Transmission (MWPT) system, microwave transmitting beam should be directed to the receiving end. Through a closed-loop regulation and control of phases of the microwave transmitting antenna unit, tracking and locking of the maximum receiving power is realized. In this paper, a microwave power transmission system with two units of X-band transmitting antennas is built and adaptively adjusting the phases at the transmitting end to achieve the highest efficiency is realized based on LabWindows/CVI platform. The center distance between the transmitting antenna and receiving antenna is 152 cm and the minimum phase shift step of power amplifier is 5.625°. Measured results show that the 3 dB dynamic range of the output power of the microwave wireless energy transmission system has been increased by 49％, and it controls the phase accurately and locks the highest system efficiency with an adaptive closed-loop.关键词
