基于线性自抗扰控制的无线电能恒压无通信传输方法
Constant-voltage No-communication Method of Wireless Power Transfer Based on Linear Active Disturbance Rejection Control
摘要
Abstract
To address the issues of low transmission efficiency and significant output voltage fluctuations caused by dynamic changes in load in a magnetic-coupling wireless power transfer(WPT)system,a constant-voltage no-communication WPT method based on linear active disturbance rejection control(LADRC)is proposed.A phase-locked loop is employed at the input of the system to track the resonant frequency,and a disturbance observation method is utilized to achieve minimum input power tracking.Meanwhile,a phase-shifted half-controlled rectifier circuit control strategy based on LADRC is implemented at the output to ensure constant-voltage output and efficient transmission,without the need of communication between the input and output.Simulation results demonstrate that a constant output voltage is maintained at the reference value under changes in load and the reference voltage,while the transmission efficiency of the system remains around 90%.关键词
